I work full time and sometimes don't have time to read all the new post's since the last visit which means when I come back all the posts are "old" and I miss some. Also, sometimes it is hard to tell who someone is responding to as there is no way to tell other than to go back and forth searching for the acutual quote. It seems that before the board at least kept track of who the reply was too, if not which post it was to.
I dont' have time to sort through all of it and make meaningful posts too, so sometimes, though I am interested, for fear of responding incorrectly, I just give up in frustration.
I find myself reading more and participating less, still very worthwhile, but a bit of a frustration.
