Twitter makes the assumption that when you follow a person, you want to follow all of their posts. But I don't think that's a good assumption — I follow a person because I want to follow a particular interest they post about.
How many of you guys are techies who just love to see your favorite tech personalities blow up your feeds with TV shows or football or politics that you don't care about?
I've always loved the way Pinterest was set up — the main focus is you follow a person's interests in the form of Pinterest Boards, not the person.
If micro.blog is truly meant for microblogging as opposed to being a traditional social network, then we should make it easy to follow an person's interests (i.e. an account's categories).
One possible solution is presenting interests/categories like this: @username/channel
So some examples would be:
Granted, most of those examples are with real-time live-tweeting in mind, but you get the idea.
Of course, the simplest alternative solution is to say, "just create another account", but keeping all categories under the same roof strengthens the main account. Plus, nobody likes to rebuild a following for a new account from scratch.
The idea is not to just "be better than Twitter"; I'm trying to solve the problem that following specific interests should be much more efficient than what is currently out there.
I'm embracing the idea that microblogging does not equal tweeting. And I'd argue that if microblogging is really about sharing content instead of having conversations, we should have more efficient ways of organizing what we share and how we follow it.
