As blogs are mostly having no-follow links, you have to post something relevant. but a much better way maybe try to exchange links with bloggers cuz those are do-follows.
I just create content for my website and post on forums once in a while. I also write articles and hubs here and there.
I spend most of my time with content creation and less with link building, ratio is perhaps 80/20 or so. SY
you do a great things dude... just keep constantly, do 10 blog commenting if you would, but keep ethically to keep strong your comment, nice sharev
I use http://sponsoredreviews.com/, add 10 reviews / day Plus i have few campaigns in http://www.voltrank.com set to 20 links / day So far all is working great
