Most of the time I read all of the posts. Sometimes there are cases in which I have a very definite answer and I want the OP to get the info right away, so I will post and let them know that I will read everybody else’s answer afterward.
I’ve found that with the relationship Q’s you really have to read everything, because often the gist of the Q changes mid way through, or you find out pertinent information that wasn’t divulged in the original Q or details. And sometimes, someone will give an answer half way down through a very long thread that really changes everything. If you don’t discover that, you may be giving redundant or foolish advice if you haven’t got the “new information.”
I’ve also discovered that the relationship Q’s tend to ask one thing and you find out later that there is much, much more going on and the original Q is only a veil for the real question.
Sometimes with food Q’s, I might answer first before reading all of the others, until afterward, because they are opinions about what tastes good. Even if you are redundant, that’s OK.
