Get the word out

Begin actively participating on online forums, commenting on other blogs, and commenting on social media networks like facebook and twitter.  Try to just be social when you are on other sites - don't try to be a salesperson.  If people like what you have to say in these places they will likely look at your blog (make sure you somehow highlight your website address).  Having fresh and original content on your website will keep readers coming back for more information and they will also be more interested in the items you recommend through your site.
