OpenACS and .LRN will not get traction unless the community pays attention to some basics:
* easy installer
* accurate documention for newbies

I can install Apache, MySQL, Moodle, Php. etc etc. in 5 minutes. The basic documentation is accurate and up-to-date. I don't have to rely on commercial vendors to get started with the system.
