Well, completely useless may be an overstatement.
The only times I actually measure ohms in an automotive troubleshooting situation, as opposed to just using my ohm meter as a glorified test light, are: 1) When I have the manufacturer's troubleshooting instructions that specify what the resistance must be on a particular piece of hardware (common); 2) I am comparing two pieces of hardware to see if there is an obvious and big difference (rarely); 3) I am performing the "jiggle" test (common).
If I'm tracking down a bad connection, I use the voltage drop test. I think that's the number one electrical test that shade tree mechanics, working on "old school" type of cars, should be familiar with. You're right, there are lots of videos showing how to use the Voltage Drop Test -- it's pretty easy to learn.
