Hey all, Heard lots of reports in the last few days that the Google-run hub is not properly unsubscribing folks. I believe I've found the source of the bug and I'm digging into it now. I also plan to follow up on this issue about the general concern of immediate unsubscription in the protocol (http://code.google.com/p/pubsubhubbub/issues/detail?id=121).
Thanks for your patience! -Brett
