How to become part of a blogging ecosystem?

So often, people create a blog, write a few posts,, and then wonder why they haven’t attracted any readers (or they create a Facebook or twitter account, write a few posts, and wonder why they don’t have any followers). To become somebody who is followed and read, it is necessary to become a part of the ecosystem. This in turn requires reading other people, commenting on their sites and participating in discussions, responding and reacting when people comment on your comments, and spreading the message beyond the confines of your blog (or social network) account.
