What to do with Windows Azure?

I got my invitation code for Windows Azure today.  Except for the PDC keynotes, I hadn’t really looked at anything Azure related.  So I vaguely have this idea about what Azure is about (cloud computing?  OK, what does that look like, exactly?), but what do I do with it?  After about a minute, I thought of doing a blog engine.  Until… my first look at an actual Windows Azure app was… you guessed it – somebody’s blog.

Granted, their blog engine is a little weak – no search and you can’t even go “back” to newer posts after looking at the “older posts” link.  But still, I can’t help but feel a day late and a dollar short.

Thus, out of ideas, I’ll still attempt it.  Maybe I’ll wikify it or something.  I dunno.  If I spend too much time trying to think of the killer social app then I’m afraid Windows Azure 1.0 will be old and tired.

Now… where to start?
