Yeah, I've dabbled in online holdem poker since, I don't know, October - so not too much experience here. Never played any "brick&mortar" games, only online. And yeah I also got bit by the bug after watching some holdem on TV... well, at least I was patient enough to do some studying before jumping in

I started out with a bankroll of about 200$, playing the lowest limit games I could find ($0.10/0.25 and so on), getting my feet wet. Kept making a little money, mostly thanks to the bonuses at the sites I played at.
Then I took part in a freeroll tournament where the total prize money was $30,000, with the top 60 finishers in the money. The tournament was open to every player at the site that had played at least 250 raked hands the previous month, there were about 3700 players in all. I actually finished 3rd of the whole lot, pocketing a tidy 2,100$!

I withdrew most of that and left about 600$ in my bankroll because I really don't want to move up to higher limits too fast, I wanna "earn" the higher limits - so, I'm currently playing limits of $0.50/$1 or $1/$2.
It's been quite a fun hobby so far, only thing is that with a day job and all it's sometimes hard to find the time to play.
