Do any of you do it? You have a few useless domains that you really bought for investment purposes, but you don't want them gaining dust, so you just run them for a blog?
I probably wouldn't do it (haven't done it yet) because once i fire up a site on a domain i have to commit to it and if i was not too bothered about the domain id just let it expire or try and sell it if i can.
I set up an automated blog on one of my such domains at http://caring-for-pets.info/ like you said it is often better than parking them
Auto blogs or splogs are worse than spams honestly, how exactly do you make money from them my good friend? O_O
You are correct they make very little. I prefer freestyle blogging nowadays. I was just giving an example of something I tried with such a domain
