I'm a looking for a social network which would let me tweet longer post (don't want to tweet longer via an isolated blog). Google+ does not and I'm already starting to hate Google+ (out of protest for their naming policy).
It's an ideal concept to sort various different interests of a single person interest into separate containers based on target audience. I think Google+ came close but their naming policy sucks. I wish they'd allow different identity/per-Circle, which could help resolve this issue. But in perspective, I should be able to target my audience based on their interest as I know best and vice-versa. Twitter is totally ineffective here to most degree.
