I'm in as well. If you stay abreast of the Alpha forums, you'll sometimes see bugs noted there but otherwise Report Everything* and describe it as clearly as you can. In my day-job, I hate sorting through 50+ reports of the same bug, but I hate it much, much less than having to sort through 1000+ after release (especially small stuff that was an easy/fast correction).

* That said, some things are clearly known or will be heavily reviewed/altered/updated/tuned (e.g., X spell doesn't have Y effect) so you might give that a pass in alpha. This is why staying up-to-date on the forums is important in alpha.
