Ok, I'll jump in.

I don't have strong feelings either, but I do have comments

1. for the historical reasons you allude to above going to a completely 
different numbering system would be a nice thing

2. I do like involving the year, but I think 2008/2009/2010 are much 
clearer then 2.8/2.9/3.0 let people shorten it verbally, but still realize 
that it's a full year being referred to.

3. avoid using the month of the release (which ubuntu does), first you 
aren't going to predict the month of relese ahead of time (so what will 
the -rc's be called, the year is fairly clear and it's not _that_ bad if 
2008.4 happens to come out in Jan 2009). also too many people don't 
understand that 8.10 is between 8.9 and 8.11, not between 8.0 and 8.2

so my prefrence (mild as it is) goes to YYYY.r.s (r=release, s=stable)
