This was submitted by a bot :D I subscribe to Fabien's RSS and he must have changed something in the server because I got this post on my RSS reader (again, as it's an old post), and here it is submitted to HN (again)

I manage my RSS by hand (I should really fix this) and update it when I am ready to publish something.

Someone emailed me to tell I had a typo in the URL of the Silpheed article. This must have unlocked the bot maybe?
