I have been working hard to become known as an authority in my website's field. I answer questions on Yahoo! Answers, I comment on related blogs (with my link), etc. So how can I tell if something is a do follow or no follow? And just to make sure I understand the difference, a no follow suggests to crawl bots that they shouldn't count your link, whereas do follows indicate the bot should crawl the links on their page. Is that right? If so, what's the benefit of no follows?
I make sure any comments I make on blogs are pertinent to the article and/or other comments and I follow up if anyone responds to me. I'm really not interested in backlinks for the sake of backlinks and sticking to related sites is important, I think.
