Matt Geri is a blogger I keep tabs on several times a week.  He brings some really great Marketing information to the table.  He recently wrote about some new niche blogs that are being developed.  What  I think is the most important point is the use of WordPress for niche marketing.

WordPress allows you the flexibility in constantly providing updated information to your readers.  That is what the search engines love.  Fresh Content.  My goal is to continue using WordPress as my publishing platform.  I highly recommend you consider it when making your next niche site.

Happy Marketing!
