What you've written is true for most topical/ niche blogs, if not all blogs really. I run my own sites, by myself. I've been doing so for years. It's not about making an income, though I wouldn't turn it down. Running a site takes up a lot of time, energy and as much money as you want to pump into it. I don't see many people making money at blogging unless they hire people to take over some of he work (publishing, maintaining or promoting) or find dependable backers who stick with them for the long haul. Last year I burnt out on my blog. I had been writing daily posts (and sticking with that schedule) for a couple of years. After being apart you will miss running the site. But, you need to consider how much you put into it versus how much you get out of it. That really is important. Not just financially but emotionally too. Anyway, good luck to you. I agree about content curation. I've got an account on Scoop.it. I tried several others but settled there. Twitter works too.
