Can anyone see the URLs of their blog commenting in Google Webmaster Tools? i.e. links to your website from blog comments. I don't see any of my blog commenting acknowledged there, how about you? I know that maybe Google Webmaster Tools does not show absolutely all links, but 100% of my forum links are there, 100% of articles are there, but 0% of blog comments - not even 1. Does this mean blog commenting is something everybody is doing but it actually does not work?
