Library clips

reQall - phone up and record audio snippets, search and browse in your web archive (as it converted to text), and RSS output…a similar service is Jott. Check out some similar sites at ResourceShelf (I’ve posted on most of these but it’s nice to have them on one list)

SlideAware - publish your slides on the web and also deliver them remotely like you can with web conferencing services, others can leave notes. Other slide sites are Preezo, Empressr, Thumbstacks, Slideshare, Slideburner, Zoho Show, Zentation
BTW, SlideShare now has audio to accompany slides (called Slidecasts)…Zentation also has video. [via DI]

Snimmer - a multi-IM web service like meebo, but in a social network kind of way…imagine if meebo gave you a public profile space, and other meebo user could chat with you. See VelvetPuffin and Hiitch for IM social networks (these are desktop apps).

Spotback cross recommendation widget - this is a post rating social network, but you don’t have to be registered to rate if you don’t want, other benefits of this widget are you can email the post, and see related posts from your blog and the blogosphere…also rate from within your RSS Reader.
Spotback engine recommends based on collaborative filtering, meaning that it uses (mostly) user ratings in order to determine what would be interesting for your readers. Therefore, the articles you write have to be rated in order to get related stories.
See it in action on one of my posts, under the comments box. Similar tools are WizAg and Sphere.

PinDax - create your own group public message board, or create one for your blog…lots of others lists in this post, these have live chat as well. PinDax differs as it’s not really linear messages, but more of a pin board or sticky note board.
