#), without the exclamation mark. But now it's a shebang or hashbang (

The new Twitter URLs now also feature the
#! symbols. A Twitter profile URL, for example, now looks like this:
#! now play some special role in URLs, like for a certain Ajax framework or something since the new Facebook and Twitter interfaces are now largely Ajaxified? Would using this in my URLs benefit my Web application in any way?
