Tools for curating unconferences?

[Evonne @amoration]

I am looking for a great mobile way to help unconference participants
curate their discoveries together. In previous years the wiki went
underfed and most of our content has scattered to the wind. This year
we'd like a single place for people to share all sorts of media
(photos, notes, video, contacts) in an easy-to-search way.

We're currently testing Flockler and Catch. Any other solutions we
should consider?
