Right; if you and some buddies want to hack animal husbandry, more power to ya! :)
And I'm actually serious; we shouldn't artificially limit the subject area. This gets back to the "meta-incubator" idea; provide a way to connect hackers who are interested in similar things, to work together, from a stable core of "we're all interested in some kind of hacking". While I may be really interested in hacking X right now, that may change. And I may drop out of an X group. However, if the group is explicitly set up to foster all kinds of hacking - well, heck, I'm going to stick around to see what else happens, and probably jump in on something I wouldn't have thought of!
