Gravatar vs Pavatar
I'm looking to implement an avatar solution for comments; something more than each user just uploading an image.
A while back Geffy mentioned Gravatar, but there have been some reports of outages and closure to new signups. Pavatar looks like an interesting idea - but I'm not sure if caching the avatars (as per the Pavatar Candidate Recommendaton) limits the flexibility of the idea.
What do you guys think - Gravatars or Pavatars?
