Here is a sample of domain ads: http://www.bussforum.org buy a domain for about $10, after a year will my domain ads make more $ than that?
It is not worth..Do you want free domain and hosting for your blog click below link http://redisred.com/win-free-domain-hosting-daily-contest
there's an antire world behind domain parking, flipping and domaining in general dedicated communities, forums, auctions and more...I think your question is a bit reductive unless you have traffic to a domain, or your domain is kind of popularkeyword.com, or you don't have a plan to monetize/resell it than it makes no sense to register it
Write a article and put it on there with some ads. Then, market that article. It's the best thing to do. Find something on wiki where you can add your related article. You will get a lot of traffic.. sure its a no follow but you will get traffic who may just click on your ad.
