Yesterday I was thinking it'd be funny to grab problemattic.com, for reasons, but discovered that the BDFL himself owns it already. lol.
Anyway, if you want to make one of those funny landing pages with a stupid domain — and have more free cash for single-purpose funny domains than I do — I made a nice list of domains which might make excellent choices. Each of them are currently available for about $12 (.com) or $8 (.org).
