I understand that Realmpop.com is a work in progress. It's certainly interesting. The breakdowns by PvE/PvP, RP/Normal, Region, Time Zone, Faction, Gender, Race, and Class are certainly things that have been attempted before, but not always conclusively. Of all of these, I would think that the Faction pie chart is the most useful so far. It can give a quick answer to "What is the faction balance on this server?"
Some other interesting possibilities could be:
by profession, by skill level/tier - That could answer what professions are underrepresented/overrepresented on this server or faction?
by population itself - how populated is this server compared to other servers?
by level - what is the distribution of characters' levels on this server?
by auction house - how many items does this server's auction houses have compared to other servers? What's the breakdown by product category?
These areas could potentially tell us where might be a good place to start an Inscriptionist character-- perhaps a server with low population, high raw materials on the AH, few Glyphs on the AH, and few Inscriptionists already there. Or maybe find where's a server with lots of low-level characters?
Thanks for your consideration!

P.S. I didn't see a forum for RealmPop, but if there was somewhere else I should posted this, I'm sorry.
