Sounds like a great name for tips from the pro players etc.
I'm sure there's heaps of people out there looking for poker advice. I could do with some for starters!
Would be worth something if developed well. No idea what though, sorry.
Not as valuable as .com. or .net versions, but from what I understand, anything to do with gambling, poker, casinos etc are worth at least something, definitely worth more than knittingadvice, lol.
Alternatively, being an 'org' it could be a simple one page site for gambling addicts. Your 'advice' could be GIVE UP NOW!, with links to suitable organisations that help with gambling addiction.
Note. Last part was meant to be funny, but maybe this could work? Hmmm...
I hope this helps in some way.
