You can create 250 character jots on Subjot and post them to Twitter and Facebook. There is also a bookmarklet that lets you share to Subjot/Twitter/Facebook from anywhere on the web.
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.
