1. DataFrames themselves? Well, I think they'll get interesting when they can 'know' about high-level entities like cities, countries, zip codes, ip addresses, etc. Basically, everything that Alpha knows and can compute about, we want Mathematica to know and compute with.
2. I used Go because I am very productive in Go and like a lot of things about it. Goroutines are neat. Java is fine, it's just very boilerplatey, and I'm not practiced enough at it to get past that. And I don't see why we can't develop a GoLink as well.
3. Probably not the whole stack, at least in the beginning. But we'll get there. We want to make it really easy to spider websites and so on.
