I have a total of 700 websites, and somewhere around 1000 parked domains, at last check. I pick up deleted domains with high traffic or ones the owners simply forgot to renew and park them and make cash through parking systems. And occasionally sell them back to the owners for a tidy sum of profit. And as far as your question about why so many sites, There isnt much reason to be in this if you aren't making money, at least in my opinion anyways lol. I started out just like you, came into the game and new NOTHING. Started reading everything I could started buying domains, hired outsourced programmers and developers, and along the way learned alot on my own. Just starting out it's alot to take in, and when I started 12 years ago it was a hell of lot more simple then it is nowadays. Just don't jump in and think your going to be able to quit your day job anytime soon it takes a few years of alot of sleepless nights to really get rolling. But honestly once you make your first dollar, you will be hooked! 12yrs later I'm making around $600,000 per year gross with about $450,000 take home. You can make yourself one hell of a life on the net if you stick with it. Your going to have 100 failures for every 1 success.
