The "nice gesture" idea is way off. By default, you need to assume they haven't opted into any sort of promotion for facebook or for your site. Treat it like private information, since their comments should be assumed to be private. Since the comments are tied to an identity, all the more reason to keep it private. I don't know; maybe you're friends with everyone in the screencaps and you are pretty sure they're okay with you reposting their comments and names publicly. ...but, for whatever reason, I wouldn't be down with that. Blank that stuff out. You know the eye dropper tool? Make rectangles of a non-intrusive color, if you don't want to screw up the design. Terrible blurring, terrible privacy, and with regard to the comment about leaving names in plain sight, terrible advice.
