Re: Why using pages for BP sections is a bad idea
BuddyPress is already a theme. Look at bp-default. That is a full WP theme that for some reason was bundled with the plugin. There is a huge mess of code devoted to making this setup work. It is nearly impossible to freely modify the templates, even if you roll your own BuddyPress theme, because the javascript is so tightly bound to the ids and classes in the markup.
I don’t think its reasonable anymore to call BP a plugin, since it does not enhance a WP site in the purest sense. It completely takes it over and defines an entirely new set of rules for how to customize the look of your site. That sounds like a theme to me.
If you think about BP as a theme, then the only acceptable ways to solve the issue and stay true to WP is pages or custom post types. This only doesn’t make sense though because BP is made up of many components that should be making their OWN decisions about how they get displayed.
So back to my original point. BP is defining too many rules, and forcing components to adhere to the default theme itself, instead of a theme prototype (which is how WP works). If BP was doing it the “right” way, then this whole issue would be moot, because each component would be deciding how its URL was determined, and the end user could decide if they liked it or not.
I think this is in the scope of the topic because it gets into defining the problem that needs to be solved, which is important before working on a solution.
