I notice that I get a fair amount of hits on my site listings about Feedwordpress’s duplication bug. I can say that while I liked it’s function in theory that I never managed to get it to truly stop making duplications in my database. If you use wordpress I can’t recommend that you use feedwordpress. The author seems unresponsive and truly doesn’t care. That’s fine we didn’t pay him and I don’t expect more.
For those that play the OMG why is this post in my database 300 times game, you know my pain. The only thing I can say is it would be great if someone made a plugin with the same functionality as feedwordpress, until then I deal with my workarounds.
