The comments on this article are great - I give huge props to Jeff Atwood for showing up, commenting, and staying polite and not getting overly defensive.
CodingHorror is no longer a daily look for me. More like weekly or monthly.
If you look back, you'll see the quality of posts went down soon after Jeff began advertising on his blog. I think that the "pressure to publish" caused him to stop trying to publish important things, but to just publish liberally to get eyeballs.
Pressure to publish? He has published 5-6 posts a week since 2004. His rate hasn't changed, and if you page through his pre-ad archives, the quality ratio is about the same as now.
