ZIMoBLOG and pingomatic
I updated the ZIMoBLOG site to use the pingomatic service instead of hitting weblogs.com directly - it was an easy change since they support the same API, and they'll ping not only weblogs.com but a number of other services for me.
Now every time a new blog entry is posted I can see http://blo.gs visit, which didn't happen before. Cool.
