Thanks for the kudos, Simon! We used to be consistently #1 in the search results for Columbo, back before Wikipedia got traction. But of course nowadays almost any word of name you search on, will get the Wikipedia entry as the #1 hit -- so I can't feel bad about that.
It's also true that some (actually, a lot) of the Wikipedia article comes from info on this site -- not just general, publicly available data, but some things (like, the story of the Trivial Pursuit lawsuit) that I personally spent hours digging-up from the law library and elsewhere. But Wikipedia does cite us as a source (the last I checked), and anyway my philosophy is pretty much like Google's or Wikipedia's -- that information should be shared and appreciated. The whole purpose of the site is to promote enjoyment of Columbo.
