this is something i feel alot of people miss (atleast in the beginning stages) because they practice/play by themselves a majority of the time.
playing with other people is a different beast, and a very crucial skill to have if you are going to try to take your music/playing further (i.e. bands, etc.)
plus its waay more fun to jam with others (esp when your skills arent that great)
i know when i was first learning guitar, i played by myself exclusively for a few months, that when I first tried to jam with other people, i had no idea what was goin on and it was tough to really gel with others even tho my skills werent that terrible (they (their skills were really good however tho).
as for teaching, one of my friends recently got a few gigs as a guitar teacher, i think they are mostly younger kids, so the situation is a little different, but he knows very little theory. he just teaches them the basics on guitar, hangs out with them, shows them a song or two. i guess the kids are more interested in showing him their toy dinosaur collection

. but they are happy, and the parents are happy so i think thats the most important thing (not skill level).
