to be honest, I dont know much about wines and even less about the technological features of a webside:), but I have seen a new webside called gurudelvino.com that is also based on 2.0 and its in german/english and spanish. Most of the wines are spanish wines and the side is still in the beta version. I think it could be a competitor of Snooth because it looks like the users can do much more things like uploading videos, create thier own groups and blogs. The only thing that could kill them is the major investment of snooth. Nut I think it looks quite good.

I will keep an eye on both and hopefully one will become a nice lively one.
