It actually makes a great reference. Today during a pair session a new developer happen to mention a technology that might solve X, Y and Z. I think 5 or 10 years ago I would have shut them down - I was much more arrogant back then. Instead in the next few days this person is going to demo something they've built since they are pretty much our team's expert in this tech - since none of the others have used it. If everything checks out, this could very well be our next large architectural shift - and that's incredibly awesome contribution for someone new. Even if it means he'll be putting in a lot of extra work and time - in my eyes that's better than turning him into a robot that wants to check out exactly at 5pm.
