What is blog commenting???
Write your comment about an article which you find interested, you can ask any quires if you do not understand any point in that Article.
Write something interested and must related to that article with your real name, if they allow give your website name while commenting.
Will get no-follow back links from most of the blogs, but its good idea to get traffic if you write and share your content with others who commenting on the Article.
