Brent Ozar had a nice post recently on starting a technical blog, well worth reading and a good addition to my collection of blog related stuff.

One of his notes that I knew but don't think I ever wrote down was to post on weekdays only - there's a huge drop off in traffic on weekends. As I think about it I'm not sure it ultimately makes a difference or not (though I do believe it looks better to post Mon-Fri) for two reasons; one is that most blog readers use a reader, so even if you post on Sat they will see it when they hit the office Mon morning, and the other (a variation of the first one) is that hits on the page will continue to climb steadily (here on SSC I see about a 3 week period when views climb, after that it's one here and there) so again, I think this is people with readers catching up with queued content.
