try to follow the feed in some widget or any feed client. not directly in the browser
I just subscribed to your feed in Google Reader and I am seeing the full posts. Feeds get cached, so after you switch to full it can take up to an hour before you see the change, depending on where you are viewing the feed.
Did you subscribe to the feedburner feeds? im talking about the normal feeds 😀 I changed them to full posts about 2 days ago!
No, I clicked on the link you have in your post above and subscribed in Google Reader and I see the full posts. It reports the feed URL as Feed URL: http://www.earth-org.com/blogs/feed/
An now I am looking at the XML feed in IE7 and I see your full articles there also http://www.earth-org.com/blogs/feed/
