Not every blogger blogs for money.
Sure, we’re running some passive ads in this site, but our only goal is to help defray the cost of webhosting. It remains, at best, an experiment. We want to find out if we can derive some amount from ads so that we can have the site “self-maintaining.” If we can achieve that, then we’re happy. If not, well, it’s not like we can’t pay for it ourselves, you know? We’ve been paying for our own webhosting for several years now – way before Google AdSense came into the picture. And with the rate we’re going, we’re likely to pay for most of it in the years to come.
But as for blogging as a means on which our livelihood depends? Not in this lifetime. Perhaps not ever.
