hide titles based on page type? I want to disable titles from showing on main content pages, but have them show still on blog post/article pages.  I was using a CSS rule #page-title to hide them, and was thinking of working from that, but it doesn't work as well in dynamically generated pages. Comparing a post page to a main content page, I don't see any difference in the preceding css classes and ids. 

How could I quickly change this behaviour?

I'm working on a self-built custom theme that doesn't have a lot of editing done to it.
If these are different content types, you could create a separate node-[type].tpl.php file for each, leaving out the title in one of them.
