I have noticed the last week or so, that I am having trouble with my feeds and Technorati. I have noticed that my posts are not showing up in a timely fashion.
It took almost 3 days for a post to show up on Technorati, and almost 12 hours for a post to be delivered through my feed.
I am not sure what is causing these issues, but I will have to ask WordPress tech support why I am having these issues. I have had good luck with using WordPress tech support so far.
