From Currents to Google Play Newsstand and the spirit of Google Reader
Back when Google Reader was in the midst of its death rattle, I assumed that Google wasn't going to completely abandon the news aggregation game, and that seems to be true. Unfortunately for those who were in love with Google Reader, there isn't yet a Google option that will allow you to easily move over your Reader world (assuming you are still holding on to that OPML file), but it does look like Google Play Newsstand is at least on the path to be the spiritual successor to Google Reader.
Obviously, if you're still looking for a complete replacement for Reader, then you obviously haven't looked too hard because there are plenty of options. The front runner right now seems to be Feedly, although services like NewsBlur, The Old Reader, and Digg have their supporters as well. But, as Google said when it first announced that it would be shutting down Google Reader, the way that most people find and consume their news is changing. Only the most hardcore news junkies or those who's job depends on keeping track of the news really need to be using an RSS reader anymore. Most people get their news via social networks, either by following news sources, or through links shared by friends.
Still others get their news in so-called "magazine" apps like Flipboard, which are quite a lot like RSS readers except that they can offer content creators more control over presentation, and they don't include the unread article count that you would find in an RSS reader. The simple removal of an unread article count is a profound difference, which makes it a much more casual experience, and makes it feel less like work, especially for those who constantly have the thought, "must... get... to... inbox... zero!" This is of course the path that Google is taking with its Newsstand app, because Newsstand really is just the old Google Play Magazines app that has had newspapers added and Google Currents mashed in as well. But, Newsstand has two major benefits compared to its Google Currents roots: design and Google Play.
Google Currents was always a fairly annoying app. It was obvious that Google could do something good with it, but never really put enough effort into doing so. There was good support from content creators, so post major publications were included, but aside from the one update which brought the Google+ style card layout to the app, there was never much visually to get excited about. The same is not true for Newsstand, at least not on the news side of things. Google obviously put more effort in and it shows, but I do wonder if Google might have over-thought some of the choices.
The first thing you'll notice is that the layout in Newsstand is more image-heavy, which really just means that the images that accompany a story have been expanded. It's a choice that gives the app more visual pop, but it is certainly a drawback as far as the app being a news reader. This is especially true when your device is in landscape orientation, because you may end up only seeing one actual headline and the rest of the screen is filled with an image that may or may not be helpful in describing what the story is about.
Another thing to note, which will be a big issue for those who love the way an RSS reader functions: Newsstand has done away with the chronological news feed that had been the way Currents handled news. Now, Google is using some sort of algorithm to decide which articles are the most important and bringing those up to the top. Google is also promising that the app will learn over time, and get better at finding the stories that would be of the most interest to you. If this works well, it will certainly help with issues of missing a big story, but for those who like to see everything, this layout could be an issue and right now there is no way to to switch the feeds to be chronological.
Newsstand is all about relevance and importance, not chronology. But, the sections bar doesn't indicate that there are more options off-screen.
The top bar for each news source is also something of a mixed-bag. It has faint images swimming in it, which is nice compared to the plain bar of Currents. It's also nice that Google has removed the drop-down menu for switching sections in a publication, but the new layout doesn't adapt well. Now, all of the sections are lined up in a row, which works well on a large tablet in landscape, even if there are a bunch of sections (like in The Guardian). But, if you are on a smaller screen, or just switch your display to portrait orientation some of those sections will disappear off the edge of the screen, and there is no visual cue to let you know that swiping will let you scroll through to the other sections, or even a visual cue to let you know that those other sections are there at all. Also missing is the option that Currents had to customize the list of sections in order to compact a longer list by removing things you don't care much about.
Another mixed issue with the top bar is the back button. The back button is always in the top left, as usual. Except now, when you are in portrait orientation, the source logo will be in the middle of the bar, leaving only the faint back button with no icon. The nice thing about it is when you scroll up through the news feed that bar squashes down, and the source logo slides neatly to where it should be next to the back button. But, before that it is a little odd to see a back arrow with no icon next to it.
Once you get into an article, Newsstand absolutely blows Currents out of the water. Currents had the unfortunate UI that was trying to mimic Flipboard, meaning that rather than having a single article that you scroll through like you would in most digital instances, articles were broken up into pages that you would slide through by swiping right and left. When you got to the end of an article, another swipe would bring you to the next article. Now, thankfully, articles are a single page that you can scroll through vertically, and swiping left and right will move you to the previous and next stories. Just as it should be. The "save" button has also been swapped out for a "bookmark" button, which does the same thing but makes more sense with the magazine metaphor.
The sources screen has also gotten a visual overhaul, which again is a mixed-bag. In Currents, all of your sources were in the slide-out menu on the left, and they were organized into categories. Now, they are just a grid of icons, which again is more visually appealing to an extent, but doesn't allow for as much organization, although it is still possible to drag the icons around to rearrange, which is nice. It seems likely that category organization will be coming back in a future update.
Newsstand's news sources page is more visually appealing, but offers limited organization.
Currents' navigation drawer didn't have the visual pop, but organized feeds by content category.
Newsstand makes a minor tweak to call saved stories "bookmarks", which is a better metaphor...
Overall, the news section of Newsstand is a better way to consume content than Currents ever was. The layout is nicer, although it does have some quirks that need ironing out. But, the other big change here is in how you get the content that you want, because Newsstand has full Google Play integration.
