I have been a bloggings tips blogger with a no-follow WordPress.com blog for 5 1/2 years now. In the beginning I made an effort to leave meaningful comments on other related blogs in the same niche. As I could not then and cannot use commentluv, keywordluv or change my comment links to do-follow there was no reciprocation from the other bloggers. That's where I remain today between a rock and a hard place. In my niche do-follow bloggers backlink to posts on do-follow blogs. Do-follow bloggers are a clique who reward each other with do-follow comments links. They will even backlink to low quality content posts on do-follow blogs, rather than backlinking to high quality posts on the same subjects on no-follow blogs like our WordPress.com blogs. Hopefully, you will be able to find humor bloggers who aren't members of the do-follow cliques.
