I do understand the role of the community user - it is a record keeping device that owns all activity that is no longer controlled by a specific named user. Even with that knowledge, however, I found this interesting:

1. Are unowned hats going to Community as well?
2. How does Community figure out what hat she's (he?) going to wear? Is it random, or, is the Crab intentional?
3. Was this intentional or just an interesting feature? Put another way, are the devs who implemented hats that on top of things that they considered this? If so, well, my hats off to you!
