Update faq.rst
Now we've got Gravatar support
Frequently asked question
=========================
-Why not use Gravatar/Libravatar/... ?
--------------------------------------
-
-Various people asked or complained about the generated icons next to their
-comments. First, it is not an avatar, it is an identicon used to
-*identify* an author of multiple comments without leaking personal
-informations (unlike Gravatar).
-
-If you are in need of Gravatar_, then use Disqus. If you run your own
-Libravatar_ server, you can work on a patch for Isso which adds *optional*
-support for avatars.
