Name: Vlog It
Font: Chopin Script Regular
This is a script font, and part of me thinks it might be a bit too fancy for the kind of site this is. I think maybe a hand-drawn or decorative font might work better. It still looks nice though.

I really like what they did with this site. The headings decorative font gives it kind of a playful detective/mystery vibe, which it looks like is what they were going for. The main font may be a little plain when paired with the other one, but that's a nitpick really.
Qwota is a nice site that uses bootstrap creatively.
Gliffy uses pretty standard bootstrap elements; you can tell because it uses the same font as Twitter, another site that uses it.
