Last night I've changed the way my feeds are handled on this blog. I've taken care of all redirections with a mix of WordPress plugins, Apache's 301 redirects and Feedburner's "My Brand" service. So everything should be transparent from your (and your feed reader) point of you.
But since this blog moved from one location to another in the last past years, I doubt everyone use the right URLs. This update is a good opportunity to check that you are using the "official" feed URLs:
For blog posts: http://kevin.deldycke.com/feed
For blog In the future, I plan to support these URLs only. So please update your feed aggregation settings ! :)
