I still need to fix the behaviour of the spoiler tooltips under IE8 and there's always the risk a new bug might creep in but, for now, it looks good and works well.
I still have quite a ways to go before I can bear to open-source this, but a lot of progress has been made to fix the oldest and ugliest codebase I still actively work on.
I have moved my FeedBurner-cached feeds to a custom subdomain I control so that this will be the only manual change you will ever need to make. Old feed URLs will continue to work for now but I can't guarantee that I'll be using FeedBurner forever.
