I have a couple of invites for Twine.com, if you want one send me an email or leave a comment with the email address you’d like me to send it to. I haven’t had time to really play with it, so I have no opinion yet.
Haven’t heard of it? From their website
Twine is a new service that helps you organize, share and discover information about your interests, with networks of like-minded people. You can use Twine alone, with friends, groups and communities, or even in your company.
