I'll bite -- improved twitter bootstrap theme! The new design is more like the traditional "fundable" SV-startup-bootstrap theme.

In all seriousness, I think it is rather bold that they include a polarizing substance (butter) in their name. Personally I'd probably avoid the issue and go with something a bit less controversial. To be quite honest, even though I eat and enjoy butter the name "Buttercoin" is a slight turnoff -- I can only imagine how the less dairy inclined feel about it.
