Because of this, it's a pretty common practice to share blog posts on social media, push the posts to feeds, and generally promote the blog. It's all fine and dandy to say that an interesting blog will attract eyeballs on its own merit, but in practice that's not how it works. My experience may be atypical, but there's two things that are guaranteed to help out with making sure that at least a few people who might be interested in the subject see the post: post regularly (because then people will at least look to see if there are posts on a semi-regular basis) and share the posts.
On Google+, at least in roleplaying circles, there have been calls to not blast a new blog post to every community. There's some overlap in community membership, and people wind up seeing the same post take over their feed. Lots of us have been guilty of this in the past, and I for one have heeded the requests of various owners and moderators to keep it to a dull roar. I tend to pick a couple communities that the post might be relevant to or might be conducive to a discussion on the topic. One of those communities is Pen & Paper RPG Bloggers, which is dedicated strictly to blogging and blog updates. That means I might choose one or two more - typically, it's the G+ Tabletop Roleplayers Community and that's it, because it's the largest and one of the most active. If it's Fate related, I might post it to Fate Core. If it's worldbuilding, then Worldbuilding or maybe a map community. Kicksnarker for...well, we all know what Kicksnarker is for.
This seems to be working for the majority. I can attempt to get the post seen by people who might be interested, moderators aren't inundated with posts that have little or no relevance, and readers don't find their entire stream covered with the same post over and over. Everybody's happy.
Then, there's this guy.

I really - I mean really - have to resist the urge in tagging him in every blog post I ever write. He's entitled to his opinion. Just as I'm entitled to keep doing exactly what I've been doing: writing posts when the mood or inspiration strikes me, on whatever I want to write about, and sharing those posts in a manner that I think will encourage interested readers. Even if that includes a lengthy post to complain about some dude complaining about posts being spam.
