I one time did a rather dull blog with tiny posts describing new blogs I found. (preferably using their own words) It wasn't a serious effort but got over 3 million hits. People didn't stick around but it was seriously cross pollinating readers between similar blogs. The other [proverbial] stay at home mum into baking cakes was just that much more interesting to the one.
I had amazing amounts of fun sending the "motherload" of traffic into 2 article blogs that started days ago. (If you knew me you would laugh how stereotypical that joke is.)
The proverbial mum was like, uhhh okay, I suppose I have to bake more cakes now?
Then when the blog matured other blogs would start to publish (much better) Articles about those awesome cakes. Even interviews happened.
I added 1-5 (usually 3) blog posts per day for a few years. Today there is ONLY ONE out of all of those blogs left that I know of. My blog died naturally, I just got bored with gazing over stale blogs and deleting postings referring to dead ones then deleted the entire thing.
Most important, I think, was writing for being pleasurable and nourishing to the reader rather than egoistically trying to impress with wit, domain knowledge, and, worst of all, personal anecdotes – the boring, herpetic poison that oozes from most blogs.
Like art, you're assembling a puzzle with no preordained point of completion. It didn't come easily but seemed clear when it was done.
