I've been playing with Kwippy
Kwippy is a micro/nanoblogging webapp + IM status logger + social network.? A bit like Twitter.
And since my Twitter account isn’t working at the moment, I thought I’d check it out.? I rather like it.
If you’re interested, let me know if you’d like me to invite you — I need your email — or simply sign-up on the site and you should get an invite shortly.
