I am currently using Feed Shark to ping my RSS feed. I have my feed from Blogger but utilize Feedburner. When I get ready to ping at FeedShark (at the RSS URL option), should I use: "http://www.shamatae.com/feeds/posts/default?alt=rss" (the original feed from Blogger) or "http://feeds.feedburner.com/shamatae" (the feed from Feedburner)
