I read a lot of blogs. The top profession represented amongst the blogs I read is attorney, because, go figure, I read a lot of law blogs. The next profession is reporter which is entirely attributable to the news blogs I read. It's the third profession that has me wondering. There are three blogs by librarians that I read on a regular basis. The Midwest Conservative Journal by Christopher Johnson blogs mostly about Piskie stuff with forays into pulp detective fiction and politics. Pygmy Puffs and Heffalumps is by my friend Zana and is mostly about her life with the odd Piskie bit. The Breda Fallacy is by Breda who mostly blogs about the offbeat, the funny and gun rights.
The only commonality I can attribute to the three other than profession is all three bloggers have a great deal of horse sense.
Addendum: All three are also funny. Is that a typical trait for librarians?
