Hi, Are you familiar with the DISQUS commenting system? I am using this, so I reply to comments on my own sites, but when logged in I can also comment on other sites automatically with my details (brand name, URL). DISQUS is an interesting system. I don't have to type-in my details on each site... and is substantially different from "login with Facebook" commenting. My question is linked to how commenting on other sites with my DISQUS can affect my site in the SERPs? I log in and comment on several sites. The DISQUS plugin seems to display my brand name with the URL as "dofollow" (am I right)? This could have a good influence on brand building, possibly could contribute to link popularity... Correct me, advise me, inform me - what do you think about SEO influence of DISQUS commenting on other sites?
