Part of the problem is a lot of us don't want "innovation" here. The limitation for the Twitter clones that I've found is none of them (including Twitter these days) have the critical mass of people it used to have.
Well it's fine to have that as an individual opinion about your experience, and we all have had experiences of great products horribly transformed through bullshit 'innovation', but surely there's room for improvement on twitter as a whole. The place is kinda a mess and the medium is responsible for part of that.
