Social media doesn't work like this, this approach would take ages. People following me at twitter like my content (quite a few of my followers do so after reading my blog, thus I assume they like my content), but the number of visits I get through twitter is close to 0, and some of them even retweet or post my stories.

On the other hand, the only promotion from the post that helps searchs results is commenting in other blogs, and not in all (because of the "nofollow" tag). All the steps I suggest has 0 net effect with search results. To rank high you either need to be linked to, be the only one addressing the problem, or do some kind of black google magic.

Finally, being both Hacker News readers, I am really interested in knowing which are these blogs (as we both read here, if they interest you they probably may interest me), and I want to see what they are about.
