"Blogs are definitely worth your time! Just post a simple comment (3-4 sentences is enough) every day or two. The real key is making sure you ping it to the many blog directories so you get the links.
I have a couple of blogs that rank higher for the main kw than my related content sites. The regular updating energizes SE spiders and may even get you higher rankings. I spend no more than 15 mins per day on my blogs, and the payoff is well worth it." Swebbie
