I have been giving a lot of thought on how to run virtual Knowledge Cafés of late and have some thoughts as to how to run them using a series of telephone conference calls but I have also been looking for a a video application similar to Skype group video or Google Hangouts that would allow up to 4 people have a conversation Café style.
Well I may just have found what I am looking for.
It's called Blab. It is still in beta but works exceptionally well - the video and sound quality are excellent.
It's really designed to allow people to host their own little chat shows and invite in participants but I think it would work well in the context of a Café.
Fine, if the Café is a public one, as at the moment all conversations are broadcast publically (they can also be recorded to be viewed later) but if the Café is private then there is no option to have a private group conversation but I am hoping that might be a future feature. If so, it might prove a near perfect tool for virtual private Knowledge Cafés!
Read more about it on Mashable and here is a recorded Blab on Blab for Learning and Knowledge Management from Bruno Winck.

Oh and it works on your iPhone too!
