Apparently, some posts aren’t showing up for several hours and then a bunch will show up all at once. They’re supposed to be spread out about an hour apart. I think it is a plugin related problem but I’m not sure. Plugins are being updated fairly often and that has a tendency to muck things up for other plugins on occasion. The posts are showing up in a timely manner for me but apparently not for everyone else which makes it hard for me to troubleshoot the problem.
So for the time being I’ll be deactivating some plugins including the Like Button plugin. You also might see Test Posts pop up from time to time.
