A lot of people just "blog for the sake of blogging." It's like the Underpants Gnomes' plan. Step 1: Steal underpants. Step 2: ? Step 3: Profit; Step 1 on the Internet is "blog". I've seen lots of real world businesses go damned far on word-of-mouth alone. The best marketing you can do is to go out and do your damned job for your customers, be a pro, be recognizable. If you do a good job and look good while you do it, people will talk about you. They will. They really can't help themselves. Writing about "society's (or whatever's) problems" and "maybe how to solve them" is not really a job, and nobody's going to tell their friends about you no matter how good you think you are at writing. Believe me. I tried. Now I work on motorcycles. And I write about them. Sometimes I even get paid for it!
