It has not escaped my attention that for most people my age, blogging is seen as a rather absurd activity practiced by self-absorbed young people who feel the need to tell the world about their feelings. I see no reason why middle-aged self-absorbed people shouldn't also use this medium to tell the world about their feelings as well, but I have been in numerous social and professional settings in which someone (typically my age or older) says to another "Do you have a blog?" or "Why don't you blog about that?" and everyone laughs at the joke.
The exceptions to the blogs-are-silly opinion held by many of my middle middle aged peers are the political blogs, which many people I know followed obsessively during the presidential election.
According to data I found online, ~ 15% of US adults in my age group have blogs. That's not an insignificant number.
In the blogger population, I am in the minority in age, gender, marital status, and income. I am in the majority in ethnicity and possibly in education. I read that bloggers are "better educated" than the average US adult, but it's not actually by very much (14.3 years compared to 14.2 years). Even so, you could say that I am in the majority by having > 14.2 years of education.
In the community of academic bloggers, my sense is that many are women, so in that context I am not unusual, though it does seem that I am older than most, at least among the blogging scientists.
Somehow I get the feeling that most of my middle aged colleagues are not going to get the urge to blog anytime soon and will not easily change their minds, but I would like to be wrong. In fact, I like to think that the people making the blog-jokes now will one day be inspired to start a cat blog, or a science blog, or a poetry blog, or a zombie film blog. They could even be anonymous..
