It surely does, but i guess as soon as your niche starts to get competitive and users start to searching these queries more and more, some sort of filter can be triggered.
In my niche, i am the only one who is playing it the hard way, which is writing 1000+ words of quality reviews on products, hand picked several blogs and persuaded them to have my posts with 1 2 links inside. Submitting in best webdirectories, related sitewide links, i persuaded people into putting up my links instead of paying, however, i have hardly any forum post or very very few Blog Comments.
I do submit my posts in twitter facebook though, but all those sites which are interlinking with their own properties and doing massive comment spam in blogs, are enjoying 10 folds more traffic than me.
