I use this great plugin on this site called FeedSmith which redirects all of my default feeds to my FeedBurner feed. It works well but I just found a bug in Safari. If you click on the blue RSS icon in the address field at the top, the default feed doesn’t get redirected so you end up subscribing to a basic default feed. This is the only instance where I found this problem.
I’m looking into the problem but in the meantime if you’re subscribed to the AisleOne feed could you please double check to see if the feed URL is:
http://feeds.feedburner.com/aisleone/
If it isn’t please update it. Thanks.
