difference btw help and wiki

[t u]

Hi,
I was wondering this for a while now. I missed a 3 month period during
the summer when I didn't follow news from ubuntu development.

and of course, now, I have no idea why we have two separate places to
look at for help (except the great forum). what's the difference between
help.ubuntu.com
and
wiki.ubuntu.com

also, if there is a significant difference between these two, can
someone document it somewhere on the front page of these two sites?

thanks :)
