I wanted to share these two websites for you guys that like shopping and posting reviews/tips on your blog:
Smart Shoppers Unite! Home - SSU Community and
Reviews, Consumer Reviews, Product Reviews - Viewpoints
I love these two websites and they're ideal to build up a following without doing too much except expressing your opinions on products/ideas/etc. If people like what you have to say (and they will most likely), they will friend you and check out your profile. You can post about your blog on your blog section there and people will most likely see what you're up to on there too.
And you get free stuff sometimes, and that's ALWAYS cool.
