As I mentioned in my post, it's not just about getting linked. It's about receiving articulate feedback and/or spreading the word spread. If a blogger in your industry writes about you, you're directly reaching out to your target audience. Emailing bloggers is free and quick. Showing up high in a search engine or building huge news aggregator following normally takes lots of time or money.

I get quite a lot of traffic from when I'm mentioned in a blog, and even from when I've leave comments. I say "a lot" in relative terms, my blog is only a few months old, but to me its a great start. I also put the site in my sig on the forums I use, which has meant crazy traffic the last few days (my blog is about the iPhone).

I think links from blogs are less effective nowadays when it comes to SEO, but in terms of driving traffic to your site, having a blog review you or mention you is still very important.
