It never fails. I had to stop reading yet another blog because it became lame.
I am not going to get into a deep discussion about blogs and their impact (since I swear, there have more articles written analyzing blogs than there were analyzing 9/11), but in my experience most blogs have the same natural history. It starts with me somehow discovering a blog I find interesting and then reading it conscientiously. This lasts a few weeks or months until some dramatic event occurs in the blogger's life ... something major with either their job, health, social situation, or whatever.
At that point the blog degenerates. The collection of well-written posts revolving around a single theme turns into a bunch of entries describing random events in the blogger's personal life. The focus of the blog is nearly always lost, because that dramatic event usually disrupted the original motivation for the blog. Then the blog starts to suck.
The most prominent example I can think of is Opinionistas, a blog written by a young New York attorney who was highly dissatisfied with her job in a big city law firm. Her blog did an entertaining job of describing the ridiculousness of life inside a large law firm. She eventually "outted" herself, and once her anonymity was lost so was her ability to write posts with any unified topic. Now -- or rather, last time I checked -- she just writes about whatever crosses her mind, and it is not that interesting.
Anyway, the reason I discuss any of this is because I just had to yank two blogs from my "Medical Blogs I Read" (since you know, making it onto my blogroll is so competitive.) I don't read that many blogs in the first place, medical or otherwise, so whenever one fizzles out, my online reading list takes a big hit.
This fate befalls all blogs I encounter, so I hope it doesn't happen to mine. But don't worry ... as long as I don't get kicked out of med school, Axis will be here for you.
