I'm surprised nobody else has responded here. Even if the traffic is miniscule and sucks, appearing as though your ad space is filled or partially filled can be a benefit, so its a good idea what you're doing.
My company is still in Alpha and doesn't fully work yet, but oh wells, I don't care. Didn't PG say to release a bare working version asap and "starting with a very crude version 1, then (f) iterating rapidly." I have a very early version of the app up on myspace.com/socialholdem -> check the app details for what I'm adding soon to make it competitive to the others. Right now its me and a friend is doing graphics. Or link to my blog if you want, because my app doesn't save the chips permanently to the database: outrunpoker.com/blog. Apps don't make crap for money, but its a way for me to get something going to be able to offer the service that I want, which is paid subscription based internet gambling, which is legal. From that approach, I can improve and grow from there. I know there is alot of room in the internet gambling field, especially with all the new changes in the web 2.0 world and cheaper bandwidth, etc. Someone can create a company that can compete with the big guys by changing the way it is advertised. Every new person I meet in the future, I will have a better story to tell than the one I am telling here. And so on...
Good luck to you.
