I don't know, but I'm sure it has. If your primary interface to MySQL is a GUI tool where you just click the "create table" button, type in a name and accept the other defaults, you could be using MyISAM tables without knowing anything about table types.
Don't forget, that 10 years of experience could just be 1 year repeated 10 times. A cardinal number of years doesn't always equate to increasing breadth of knowledge.
