I've been amazed at the amount of content that I am getting at SQLServerCentral. So far, in 2009, I've received over 70 articles, usually at the rate of 10-12 a week. Granted some of these are resubmits based on comments I've made, but that's a lot of content.
I used to worry about getting enough content, and that's one reason we re-run things on Friday. However it's getting to the point where I can almost run 2 a day, and I might do that one some days, especially Fridays, going with one old and new.
I welcome the submissions and I'd like to help people get published, but I'm failing miserably on my goal of getting to articles within 7 days. Right now I'm struggling with 14.
