Nice coding and great initiative man.
I'm fairly confident that I meet all your criteria, although I can't say for sure if I'm an asshole or not! Somone else will have to confirm that bit :)
Anyhow, I post regularly mainly to music, sportstalksocial, haveyoubeenhere and beer and then randomly to some other tribes... Hopefully I meet your criteria for this, if not, no hassle, thanks anyway and it really is a great initiative and at least others will benefit from it.
It all looks alright to me, I see you like your Guinness. Being from Ireland, it couldn't be anything else! You are added.
