Answer 1

I'm not that familiar with CF, but the way Facebook does it (in affect) is have an Apache rewrite rule that redirects pages that match /text3423 to /profile.php?username=text3423 (not really, but that's the basic implementation.)

Twitter uses the routing of Ruby on Rails, so really, there are no actually directories at all. It just maps /* to their user feed page.
