It seems like after every upgrade - the news feeder application (where RSS feeds are posted into a forum) freaks out and forgets where it last left off. I lost a ton of FaceBook users when my RSS Grafitti was overwhelmed with 100s of "new" RSS feeds from my site when in fact they were already posted six months earlier. My Twitter account also re-posted "new" feeds which were old as well. My Porta page reflected "new" threads which were six - seven months old. I wound up going back and deleting hunderds of duplicated RSS news feed posts and then cleaning up my fan page.... Any ideas?
