I think it's a good resource to have forums for help but I wonder how many students take the time to work out the answer themselves these days?
There are many who will work at it with only a direction given and some 'landmarks'. I give them thumbs up.
The others hurt themselves by not learning even simple things. I can't help them. I can only make them more dependent.
What kicks me is how many of that second-type-above dweebs end up in 'management'.
