Well, that’s the biggest generalization I’ve ever heard…

I’ll admit I’m not a huge blog fan. But the one time I did decide to follow someone’s blog, I found it very interesting. It wasn’t because my life was uninteresting, it was because he was a friend of mine and he was traveling South America and starting a blog following his travels, complete with photos and everything. Since South America is a place I’ve never been but desire to go to, I found it especially interesting. Additionally, the blog I followed wasn’t the typical 30-something-year-old mom uploading 6 gajillion pictures of her toddler-age kids every day, nor was it the “rant about politics” blog. I suppose you could say I was only interested because it was a travel blog and because he was someone I liked.
I’m sure you’re correct in that some people do follow blogs because they’re bored and they have nothing better to do, so they choose to read about someone else’s life that they may deem slightly more interesting than theirs, but that isn’t always the case at all. Other people may simply be friends about the person and enjoy hearing what they have to say and keeping up with their lives (whether it’s political/editorial or if it’s just daily musings). It’s not much different than coming on a site like this or going on Facebook…
Before you question why people read blogs, you should question why people write them as well.
