Have you tried Disqus yet?

I visit a large number of websites every day as part of my research and marketing for companies. You will now often see a link to Disqus. This is a community resource that has significant benefits for marketing. I would suggest you first create your profile, then when you make posts your details are available to all other viewers, which has link direct to your website.

For this and other marketing ideas please see the Business Networking page on my site.
