those types of domain are indeed more suitable for developing.
there are just too many forums nowdays.
I suggest you create a Web 2.0 site about Hosting.
First create a list of all the hosting companies.
Then allow people to post their negative and positive remarks.
Create some sort of voting system. So the highest vote and most positive remarks will make it into the front page like digg.
If you can do web 2.0, there is massive potential for your domain, cause everyone will like to post their views about their current hosting company.
then, sell advertising space, and you make big bucks.
sell text link ads, google adsense and make even more money.
then, market your domain in every way, and your site will become the BIGGEST HOSTING REVIEW site on the internet.
Massive potential there dude.
