Ribbit - Voice 2.0?

Over the past five years a number of companies tried to pull off the concept of making voice a web service.  None of them quite succeeded, for various reasons.  Now with Web 2.0 being all over the place Ribbit seems to be the new kid in the block trying to do the same albeit with more 2.0ish buzz words.  Apparently they have done well in getting VC funding - but then all others like Sylantro were well funded.

It'll be interesting to see if this one too bites the dust at some point, or we will finally have a voice 2.0 platform...
