Gittip is a site for multiple communities, not one single community, so I take it as a sign of strength that we do in fact have multiple communities using Gittip now. Think along the lines of PayPal or Twitter: they are a big tent.

I've added a +1 for you to https://github.com/gittip/www.gittip.com/issues/1074, because you're right that the homepage currently conflates the different communities that are using Gittip.
