One way I think of MapThread is as follows: If I wanted to use Table but
instead of having values evenly spaced I wanted some odd assortment of
values given by a list, then I really want MapThread.
If I want to combine two lists of equal length, pairwise, to get something
else then I want Inner.
These are probably the most common applications of the two commands.

Matt, to be honest, I don't really understand the details of how
MapThread (or the others) works. I just know that when I see
expressions of a particular structure and I need to transform them,
they might be amendable to certain commands...
I then try a few of them until I get what I want. That is probably not
the best way to go about it, but, eh... o well.
