There are lots of reasons to write blogs. Your reasons though, usually predispose the result.
I blog because I love to write. This business of building thoughts together by stacking words one after another fascinates me and fills me with a bit of stupid glee.
Since this is my motive and because I am a compulsive observer of the world, I'll never run out of things to blog about. My posts won't always be that interesting, but I could easily do several a day without noticing the missing time.
Others are chroniclers. They simply like to record the day's events for audience or audiences unspecified. I'm convinced the impulse to do this has something to do with how the brain converts short-term memories into long-term ones. It's a natural, often pleasurable process, and as long as they don't run out of days, they won't run out of things to blog about. If today wasn't interesting enough to write about, they can always pull up something that happened before they started the blog.
Fans make great bloggers. There's something out there they love, and something they love talking about--often more than they're able to find people willing to listen. so the blog gives them a platform to talk endlessly about how much they love NASCAR or Star Trek or knitting or whatever without anyone rolling their eyes and changing the subject.
Some people are frustrated in life, and they suffer encounters where they just aren't able to get the upper hand, so they blog about it in revenge. There are any number of hate blogs in reference to SecondLife. The Turd List, the Leslie/Ziggy Hanja Hate Blog, even Constance has her own blog about how much she hates us.
The problem with hate blogs is that, even though they may feel infinite amounts of hate, they don't have infinite things to say, so after the first few posts about how much they hate whatever they hate they suddenly find themselves with nothing else to say, but a blog with only four or five posts isn't very likely to garner very many readers, people may check back for a while to see if there's anything new, but eventually they'll abandon the hate blog and it remains forever floating in cyberspace as a monument to some butt-hurt soul left with no other way to vent their frustrations.
