I'm rooting for App.net, but I highly doubt that the post-Twitter era will simply involve a comparable Twitter replacement.

Personally I believe that the post-Twitter days will involve a shift away from micro sharing towards long form writing and better ways to have discussions with peers.

We have that. It's called blogging, and it came before Twitter. In order for you theory to make sense, you have to explain why people moved to Twitter in the first place, and/or if there is an uptick in blog activity

Blogging is not sharing - blogging is a GET, sharing (in the Facebook or Twitter formats) is a PUT.

To read new posts I'm interested in, I have to remember to bookmark and revisit the blog regularly. I don't have a convenience glance-view of what's new in my personal blogosphere. RSS was intended to solve this, but never really had much mainstream uptake, and I don't suspect it will now either.

The real addictiveness of Facebook and Twitter come from the fact that they are capable of constantly providing you with a stream of interesting content, filtering out that which you don't like and floating up that which you do (the mechanisms for this between Twitter and Facebook are quite different).

Until blogging can have the same thing (tumblr I suppose is somewhat like that, but is still somewhat of a fenced yard for its own community), it won't be the same as sharing in the modern context.

I'm rooting for dozens of similar, federated services that interoperate an operate on levels comparable to twitter, facebook, and wordpress
