LEP's post about the demise of chess blogging caught my attention. I've seen it too. I am a part of this falling off. Earlier this year (March-April-ish) my attention to chess blogging (reading and writing) decreased significantly.
In my case, there are number of reasons why. Right now I'm beginning to finish off an 18-month job position that requires me to work shifts. Hopefully I'll be done with this job early next year. The shift work has greatly disrupted my on-line chess activities. I mostly play correspondance chess now.
My family is continuing to grow up. Two kids are on school, one is in pre-K. They have a lot of activities going on and that takes a lot of time.
The last reason why I've decreased time with the chess blogging scene is I've sorta lost interest. I want to spend time on chess, but with so many other "distractions" I've not thought a whole lot about chess (not like I used to). Also, the Knights Errant seems dead. There isn't so much attention to them any more ... and nothing new (on-line) has replaced their gusto and fervor for chess.
One other thought occured to me ... I continue to peruse the chess blogs via bloglines. I agree with LEP's 2nd point ... there is a LOT of chess content on-line now. Information over-load might be another reason for the drop in interest. The vast majority of posts are *yawwwn* boring ... seen that, not new. But once in a while, there is a great post and catches my attention. I used to do "Chess Around the Net" posts and try to find out-of-the-ordinary stuff about chess. I still attempt this exercise, but more often than not, the stuff I find is old-news or not really blog-worthy. I might try it again tonight just for kicks.
Anway ... that is my two cents on the subject.
