http://www.diigo.com In my previous post about BLAGs, I had thought the best way to collaboratively discuss links and articles would be through taking all your bookmarks and feeding the into a blog, where you could post comments.
Diigo took one of many attempts at the social bookmarking phenomenon and succeeds at creating an intuitive interface for facilitating conversations through social bookmarks. The commenting engine is quite fun, and unlike Shadows (a seemingly more sophisticated and complicated site), where I couldn't figure out how to find my friends, I was able to connect to them quite quickly for fun multiperson dialogues. I had previously taken a quick look at Shadows for its "shadow pages" and commenting, but it really left something to be desired. Diigo then came in and hit the spot, though all of these services are blurring together.
I also stumbled across a very useful application for this software. I've been in the midst of a very difficult apartment search, and I realized that Diigo could provide a way for me to take notes (and share these notes with my roommates) across multiple listing platforms (Craigslist, Citicribs, or directly on the landlord's site). I could envision empowering all the apartment searchers across the city to provide feedback, share tips, and fight back against the brokers that have a monopoly on all of the information.
See pictures here.
I didn't stress test this apartment search information tracking application too much because I stumbled across a more elegant solution soon there after. In the meantime I will continue to poke around with Diigo, and maybe I can finally get away from Del.icio.us, which has been driving me crazy with its extremely slow searching.
