it will probably we usefull to other users
How can a primate get usefullness from the information which he does not know about ?
Well, i can assume that not knowing about something
is probably usefull for monkeys because they are not needed much in Knowledge.
But Humans do need.
For example, I do Want to Know All.
For the sake of Humans I prefer to post to public forums..
even if e-mailing/messengering seemed easier.
It is possible to make public forum posting - as easy as e-mailing,
and much more convenient and usefull. Isn't it ?
