I contacted Feedburner support about a full text feed issue, and received a helpful and quick response within 10 minutes. They explained that feeds are limited to 256k and suggested reducing the number of posts or post size to stay within the limit. I am very impressed by their responsiveness to public feedback.
My Feedburner full text feed is currently broken and I'm unable to identify the source of the problem. This has led me to consider moving my blog away from Feedburner.
I encountered an issue where my FeedBurner RSS feed wasn't displaying any article content. I've implemented a fix, and you should now be able to access the feed through the FeedBurner icon at the top left of the title. Alternatively, you can subscribe to the ATOM feed at http://www.kinlan.co.uk/atom.xml.
