Snipsly is a great place to gain some exposure in the Search Engines. By posting here you can gain some traffic and exposure from inbound links. The community is supportive of constructive content and, if your site is worth talking about, it could lead to posts from other writers. It is also decent for SEO purposes because you can chose the anchor text to your website. This should help with relevance scores in the search engines. Also, it never hurts to make a little bit of extra money from the posts that you put out there.
For Search Engine Optimization, I think that Snipsly is a pretty decent tool overall. Give it a shot..
