If you have a high-traffic site where the difference between reading a 6kb compressed php-script or a 8kb formatted php-script makes a huge difference, this cms isn't right for you anyway.

Words can't begin to describe what a bad idea it is to have comments semantically significant, as http://cms.thewikies.com/pages/how.html shows they are.

See JWZ's take on such things: http://www.jwz.org/doc/cddb.html

Huh? It looks like comments are used for template processing, just like Apache SSI does. The jwz link talks about a completely different situation.

It looks like his code has no error handling of any kind and will be incredibly non-robust against any kind of malicious/invalid input.

PHP is basically fine, but it is not the language of choice when you want to get a lot done with very few lines of code.

This prompted me to ask what lightweight CMS's everyone recommends: http://news.ycombinator.com/item?id=700031

Thanks for starting that one: really opened my eyes to a new set of CMS possibilities.
