I don't know anything about Comet or WebSocket, and the mojolicious homepage doesn't target these sales points at all. In conclusion mojolicious.org is not targeting me -- the early adopter type who *already* uses an mvc framework that he is fairly happy with, not to say I couldn't be more happy with Mojolicious. Instead you're doing what everyone is still doing by trying to target the dwindling audience of PHP users. That's what I see as the fault here. Your homepage is not noticeably different from any other mvc framework with generators.
No offense, lets examine my thought process as I traverse through your features:

    * Full stack HTTP 1.1 client/server implementation (nothing new. s
+ales point in 2003).
    * Builtin async io and prefork servers (cough??  explain.).
    * CGI and FastCGI support (nothing new. Catalyst too).
    * Code generators (Catalyst too. expired sales point in 2003).
    * Very clean object oriented API (Catalyst too. subjective).
    * Pure Perl (at best a moot point) without any hidden magic (which
+ is what everyone claims).
    * Example MVC web framework (Catalst, Maypole, Jifty et al?) named
+ Mojolicious (the name has no bearing) (aka. Perl on Rails).
