As more than one member / reader has complained about, there are currently some intermittent problems on Planet Atheism. Added to the occasional "duplicate" post, there's a new one now: some posts are linked to the wrong blog, and usually to a very old post.
I've been deleting and re-adding those manually, but it's happening more and more, which suggests that it's size-related. I'll try to contact the author of FeedWordPress again, and let's hope that a solution can be found. If not, I'll probably have to change software... again. :(
Meanwhile, all I can do is ask you to be patient, and I hope you still find PA useful, even with these temporary problems.
