Blogs have a great potential. The best feature according to me is the content relevant urls of blog posts that helps quite a lot in grabbing traffic from search engines. You can get a lot of traffic if you actually just continue writing on your blog and get a few relevant quality links to point to your blog. RSS feed is another method good method actually.
Another good method is to link to blog posts of relevant high traffic blogs, so automatically link to your blog post will appear in their "Post page" that shows as "Tracbacks"
