When people were blogging because it was fun for them, the world was full of various content. Once a few got rich (or at least well-to-do and famous) from it, it all went to hell.
If you're blogging and worrying about "how will readers find me" you're doing it wrong, and are basically doomed to fail.
You blog because you like to write, and readers will slowly accumulate over time. Comments and/or a small forum can work wonders, too, as long as you're protected from spam.
