If I could, I would just Tipjoy Twitter so they finally create the grouping. I understand the big "message bus" idea they are selling and that they are focusing on the core, the scaling, the uptime, etc. But seriously, when will they release the groups themselves? Isn't this a core functionality?
I have friends, colleagues, family, local community, egos, randoms, etc. there. And it is quite a mess.
It depends on what you mean by grouping - it's not exactly as easy as it sounds at first blush, as outlined by Twitter's Jason Goldman at Getsatisfaction:
