Like many here, I've lamented the loss of ability to filter out forums which hold no interest to me. I have discovered a mini-cure, somewhat drastic, but it works. A lot of threads are started by "evangelists" within the forum. If you ignore that person, the threads they have started disappear from your "Recent Posts" feed, and all subsequent posts by that user go away. Limited in functionality, but I no longer see "Phone Friday" threads.
