I'm here to be of service. I've been an editing since September of 2004, and an admin since November of that year. It appears that arbcom is likely to end up rather larger than it has been in the past, and that's a good thing; with a larger arbcom, the work can be divided and conquered (though of course the procedures will need to be changed.) This will lessen the load on each arbitrator, thus reducing arbcom burnout and speeding up arbcom throughput.
I don't really care what the selection process is. I think I can be very helpful as an arbitrator. I pride myself on being good at understanding both sides of a dispute; I also pride myself on being able to recognize when a dispute exists primarily because one of the disputants wants a dispute.
I think arbcom is doing a pretty good job at the moment but could be doing better.
I've been involved with online community, generally in a moderating role (as sysop of my own BBS as well as a host of many conferences on the Well), since the late '70s. This experience will be useful if I'm asked to join the Arbitration Committee.
