Since the release of 1.5, WordPress has included an “update-links” program that you can call periodically to check the latest updated time of the links in your link roll. This program queries Pingomatic, which returns a list links and update times.
However, if the links in your database are of the format “http://www.timeistight.com,” the Pingomatic API won’t recognize them, even if the site pings Pingomatic religously; the Pingomatic API responds only to links without the “www,” e.g., “http://timeistight.com”.
I first caught this in the forums, and immediately went to my Links Manager. It worked! (Thunderous applause: Time Is Tight)
This solves the following posts: Update links, Not all blogs updating?

Now all I have to do is sit and wait for the DNS settings for my blog to update as I changed hosts….

wtf, I didn’t know about update-links ??!1 And since I had upgraded from 1.2 to 1.5 it now works, blogroll links updated \o/
But, do you still have to call update-links manually ?

Ozh: Yes. Setup a cron job to do that once every hour.
