Top 100,000 domains by age as determined by current owner? That's finite and maybe weighted to seniority of concern?

Wouldn't most of those domains be owned by speculators? I doubt very many legit organizations own more than a handful of domains.

Actually, there are a bunch of large non-profits that register one domain per local chapter, and have thousands of .ORG domains. There aren’t a lot of speculators in .ORG compared to other gTLDs, because there’s a perception, probably correct, that non-profits don’t have deep pockets to buy domains from speculators.
