Tweetbot update takes a cue from Slices
The new "media view" as it is called is quite nice, but a bit limited compared to Slices. Right now, it only seems to support image links from Twitter, YFrog, Instagram, and Flickr, and video links from YouTube or Vine. Additionally, it's a bit annoying that you have to scroll to the top of your feed in order to toggle the media view, rather than being able to trigger it anywhere in the timeline.
The update also redesigns the image viewer in the app. It's a nice start, and we're interested to see where it goes from here. If you want to give Tweetbot a try, it's available for iPhone and iPad for $2.99 each.
