I didn't see a thread like this here, so I will start off.
I run a profitable forum in a high tech niche market (posforum dot net)
I sell ads in the right hand column for $99.00 each per month. Pay-pal subscription ONLY.
The ads were sold via email marketing and cold calling, more hopefully will be on the way
Right now that forum makes me about $500.00 per month.
I have an ecommerce site I am launching to sell a very uniques packaging product. This should launch this month.
Third, I own a lawyer directory that will take years to make me any money.
Fourth, i have started some microsites.
Other than that I also work a full time job that pays me well.
Ok, everyone else, lets hear it!
