For Reference, doing some positionning on Textpattern's forum :)

I’ll try to do this kind of comparative analysis the other way around based on MODx (I’ll probably need help here from ex or current Joomla users... I think our main competitors are Drupal and Joomla, at least that’s what the competition thinks ). In the meantime, here is some comparison of textpattern vs MODx and CMS Made Simple... Thought I would share !

Also, check new development on the previous MODx thread on Textpattern’s forum, I have attracted some interrest from quite talented members of Texpattern’s community (hakjoon is a particularly good plugin developper... and great contributor... I got his attention there )
