So to be clear, the cross posting pepole have a problem against is when they do it on multiple forums at once?
What if they word it deferent each time, is that deferent? Or is the fact that they don't "trust" your advice what makes pepole mad?
How dose it waste your time? Do you not post if someone already post an answer? What if after they post it online and they find the answer in a book or soemthing, is that bad it waste your time still?
Why is it a bad thing to post something in two forums, you will get 2 times the answers, and sometimes yeah it will be the "same" but you know what, go on any forum and look at it, must pepole post "I agree with (enter name here) and then post their own wording of the problem, your getting 6 deferent wordings of the same thing.
For proof go look at my "help with this code" post in C++ I had four of all say I needed == instead of =, and need to put no in "no". This happens ALL the time on all forums, did they add much besides the fact that my spelling and grammar stink? Not really, thats not to say I don't value the help, I'm grateful for it, but the fact remains none of them add much to it besides awning the problem the same way in deferent words, even with seeing the other posts they are similar they all said , = is for assigns and == means "equal" and no needs to be "no".
Was mine trivial? Sure, yeah it was, but as been said what is trivial if you don't know it? Did I know the difference between = and ==? Yes, I've used it on a few other programs, I just never saw it while proof reading the code.
But thats not to say I'm saying cross posting is bad or not, in fact, I'm unsure as to which side I'm on. On one hand I see it like this, its like looking for a job, its okay to send out 4 defreint aplcations to defreint jobs, but it is polite to let them know when you get the job. Then there is the its also polite to tell them upfront "I'm lookign at other jobs to". So I have mixed feelings, I would not say its "wrong" or should be aginst the rules, but maybe its not polite, I might go with that but as I said its really a hard thing to pick a side.
