Yeah, I just saw some of the things he wanted to do, like adding an ad free service (I assume monthly subscription), adding an edit button for tweets and a few other things. Makes sense.
I guess. Twitter has explored those things - it's not like they're revelations. For example, one problem with the edit button is how it impacts likes and retweets if someone can change the content. I have always thought a 60 second edit window would be good to fix typos but there may be technical hurdles there too (typos can be resolved by taking the 60 seconds before you post not after).
