Man, I feel weird. I used BS2 temporarily, but then stripped it out for a straight reset and grid system. Old habits die hard, I guess, and what I Want from a UI doesn't always match Bootstraps ideas... I'll give this another shot for my startup prototype, but I have a feeling the same will happen. Is anyone else like that, or am I now old-school at the ripe age of 22?
I'd recommend Foundation as an alternative too, but that one's already been suggested. It's also very good, but slightly heavier-weight than Skeleton.
