In wordpress, this is fairly simple.. download wp-autoblog, install it, and key in the feeds you want to use…

you’ll then end up with something like mygagdetinfo.com or roykeane.net……

those two are my sites.. and they’ve both had problems.. one was hit with a copyright infringement case, the other has been sandboxed by google for duplicate content.

So unless you know what you’re doing, it’s a risky business. One i’ve learned from. I no longer use full feeds as content, as that can be misleading.. so i use partial feeds, with just text and always include a link back to the original author. This is *usually* safe enough.
