I agree with you that Mike Collins is not forgotten.

Wouldn't it be interesting to know what proportion of the population can name all three astronauts on Apollo 11, both of those that walked on the Moon, which it was that was first, or none.

But then again, how many here on HN can name all twelve who walked on the Moon? Does it matter who they were? They were, after all, as Neil Armstrong says, just the most visible of the half million people who made it possible.
