If you’re a blogger and got a trackback from this post or linked to us, please check the link you put in from this post. We just realized that WordPress operates different from Powerblogs on changing a post’s date. On Powerblogs, we could change date and the old link worked. It turns out that when we redated that post it assigned a totally new link to it — which means it’s likely if you linked to us last night, that link no longer will take your readers to the post. If you want to link to our post, you’d have to relink. This may alter the way we do this site.
