I'm fast approaching my 500th FTF and I have been caching for less then 2 years sometimes I share them and sometimes I don't just depends how I feel at that moment but as far as I'm concerned, who finds it is the FTFer and it is totally their call most of the time we don't share. Thought I would add ......yes always share a FTF with a buddy I'm caching with in fact I think I even shared one with Bittsen one time but if I show up and there are other people there or show up while I am looking and I make the find totally my call.

interesting topic
I got to agree with Scubasonic you find it yours just like the kindergarten saying "Finders keepers losers weepers" unless your cacheing with a buddy then i could see using the Co FTF
