* Full stack HTTP 1.1 client/server implementation (nothing new. sales 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).
