Crowdsourcing: Facebook Connect vs. Google Friend Connect

I am thinking about adding either Google’s Friend Connect or Facebook Connect as an option for people leaving comments on this blog. Either technology gives me what I’m looking for: a way for people to “join” a community without having to remember another password. The problem lies in not knowing which audience I’m doing a disservice to if I adopt one over the other.

Help me figure out which one you would use.
