Do you think forum and blog posting work for SEO ? ?

[javaid.sandhu6]

I am posting regulary in forums and blogs that are Do Follow. But today I read one article where someone says google doesnt count these links in blogs and forums.I am a bit worried I am wasting my time, because my concern is mainly for Search Engine Optimization. So I ask here maybe something that a lot of people has asked, but I want opinion from people that work on backlink building that way if it works for them.
