I'm part of that crowd.  I had heard of bitcoin before, but this is what really got me interested.

I decided I liked the original client better than the one that Google made.  I haven't bought anything on the exchange yet though.  I prefer to offer my services in exchange for bitcoins, and then spend the bitcoins on other services.

I'm an avid tor user, and was hoping that bitcoin could provide me with a bit of anon money.  After reading the thread on anonymous use of bitcoin, I am a bit worried.  I can see services like bitlaunder fixing my problem though.

Anyhow, I am a PHP developer, and as soon as I have my own computer again (mine was stolen), I am willing to offer my services to the cause.
