There are a lot of unanswered questions. For example, there is some speculation that users will be able to select between keeping the status quo, or shifting to the algorithmic feed. Also being examined closely is the site's 140 character limit on messages. Last month, there was talk that Twitter would go to a 10,000 character cap for tweets.
There are some Twitter users who are against Twitter raising the character limit. These are the traditionalists who tend to see any change as being bad. Currently, Twitter employs a 10,000 character limit on Direct Messages sent between two Twitter members.
Thanks for the tip!
