I guess 500 Watchers is a milestone that should be marked in some way. Obviously it's nowhere near as good as 256, but we can't stay tied to 8 bit binary forever, can we, unless we ignore 500 and go for 512 as the milestone, but 9 bits is messy. 16 bits is a nicer number, but we could be waiting a while for 65,536, so maybe we should just watch for 500.

Any suggestions of a thing to do to mark 500?
