It seems very popular, so maybe it's just that I'm not cool enough (not in the target audience/mixing with the right crowd, virally speaking) - but being upfront about what something is and what's great about it, would seem to me to be an important for encouraging adoption. OTOH, I'm noticed many successful projects don't do this, so maybe it isn't important. :/

My history shows 5 pages from the landing page before I found one that said what CouchDB is (the faq), and I'm still not sure what distinguishes it.

btw: awesome logo and poster.
