LiveJournal
This is mostly a rant about how LiveJournal sucks for syndicated accounts. First it looks like LiveJournal kind of hacked syndicated accounts onto the system. You can't do anything with one once it is created. So if you have to send an email that's a PITA but manageable. The part that really irks me is the fact that LiveJournal has comment links on syndicated entries. Those comments however are LiveJournal specific and don't tie back to the original entry at all. The best part is that once old entries have rotated off of the syndicated accounts, bye-bye comments. So not only does the original entry poster not get the comments, they soon become lost in the ether!
