Web app Twine (currently in closed beta) attempts to bring social search and bookmarking tools to the wiki, which sounds like an interesting combination. The app offers personal or group knowledge management for sharing, organising and searching for information, includng bookmarks, images and videos.
Web Worker Daily wrote about Twine the other day, and described it like so:
"A 'twine' is similar to a wiki, in that it may be specific to a certain subject or project, can have multiple members, allows for permission-based updating, and supports moderation. You tag the content you add to Twine, but the twist is that it tags your content too, by using natural language processing to figure out what it’s about."
Twine is in private beta at the moment. However, I got in touch with Twine PR to find out if it would be a free or paid app. The word came back that Twine will always offer a free (ad-supported) basic version, as well as a subscription-based professional version. Good stuff.
