I am selling my gambling news blog. This site has started over the last 2 months to earn revenue from text-link-ads.
The site runs easily on wordpress using a cron job to run smart RSS which then in turn gets news feeds from various sources and posts them onto the blog.
The site requires absolutely no maintenence to run it is self sufficient.
With a little TLC and some backlink building im sure this can grow to a lot more as people with gambling sites ar forever paying pretty high for PR links.
