I've noticed a lot of topic dilution lately. You'll read an interesting title but when you look at the comments, it's 90% puns, jokes, references, etc., which is entertaining to read of course, but totally kills analytical debate and further research/discussion of the OP topic. One of the greatest things about this community is the peer review/discussion and I've noticed an extreme shift away from that over the last few days which is a tactic of forum infiltration.
