re: Sure
If you are puttering on these boards during work breaks, as I do, sometimes you pore over all the threads in detail when things are slow, and other times you skim over them quickly to see if anything new catches your eye. What catches your eye varies depending on mood and what you've been discussing on other threads. And sometimes you can go for a couple of days without hitting the boards at all. There is no consistency to this at all.
So sometimes I miss something, and sometimes I post something that someone else has already linked to. Hopefully, nobody gets too miffed at me. ;)
