Well I found the proper ping URL, http://ping.feedburner.google.com/, and it looks like everything is supposedly working as advertised. No doubt I'll be keeping an eye on things for the next little while…
Google Reader also seems to be a bit slow too.
EDIT: Nope. 37 minutes after publishing even with the ping and Feedburner doesn't have it yet. Changing plugins for giggles.
