[CoastalCoder]

I'm a fairly senior member of a development team whose programmers have a big range of skill levels.

One thing I've found personally rewarding is having to articulate why I believe certain designs / choices are bad ideas, and be ready to propose better alternatives.

If all of my team members were equally experienced, there would be much less need to do this. But it would probably mean atrophying the knowledge underlying my gut instincts, and not being so open to valid alternatives.
