1. We cannot diagnose your feed when you're using FeedBurner. Turn off the FeedSmith plugin before telling us about it. Your feed link is this: http://www.money-hawk.com/blog/feed/ and until it stops redirecting us, all we see is your FeedBurner feed. FeedBurner is not our problem, we cannot help you with it.
2. Full feeds DO WORK. However, you may have trouble seeing this at first when you switch it over, because feedreaders tend to cache feeds.
Really. There's no magic trick to full feeds, you're just overthinking it. All you have to do is to turn it on. But you may not see immediate results, and if you're using any sort of feed plugins those can interfere as well. We can only prove this to you when you're not using any of that stuff that alters the feed output.
