I can't think of any reason why the add to any code is showing up in just one item in my feed. Check it out:
If you look for the item from 2/24/2008 (the top item as I type this) I see "a2a_linkurl=" etc.
Is it just that the text in the post is too short? I think this is the case since a check of another feed shows the "a2a" code in every post.
See what I mean here:
That's the feed for my Twitterstream--so, all the posts are too short. So, is there a way to exclude your "add to any" code from the RSS feed?
