I'm interested in Quora as a potential friendfeed replacement for the day when facebook pulls the plug, or the service becomes so unreliable it's no longer usable. The value of friendfeed for us is that it is so similar to facebook that students need very little training in how to use it - but by using a parallel network we don't intrude on the facebook social space. Quora has a different architecture but may have it's own value. More importantly, it's clear that trying to compete in the facebook space is not a viable business model, so that's another reason why Quora is interesting.
I need your help to test it out: http://www.quora.com/AJ-Cann Can we grok this?
