Thanks to Wiley colleague John Helmus for pointing this link out to me. Jeff Atwood, author of the Coding Horror blog, provides a nice list of 13 bad blogging practices. I'm guilty of implementing several of these, but in honor of Jeff's list, I'm immediately removing the calendar element from my blog (item #1 in his post).
I have to admit that as I read each of the 13 items I immediately thought of at least one or two offending blogs (including my own, unfortunately). Take a look at his list and see if you have the same reaction.
