Like most blog software, WordPress will ping a list of services each time you write a post. I’ve spent the last hour or two refining my list and I think it’s pretty solid. Feel free to use this on your own blog if you’d like. in WordPress, just go to [settings] and then [writing], and there is a box near the bottom that says “Update Services”. Just copy and paste this list into there and you’re done!
If you have any other additions that you feel deserve to be on the list (or if you think some should be removed), please leave a comment and let me know.
