I've noticed something over the last few years, nearly every company I'm at, with nearly every project I work on, with nearly every new hire (regardless of skill/experience level) wants to do something 'different'.

It might be the coding standards or the overall architecture or the language or the methodology. But it's always something. A lot of times, it's just stating the obvious, 'Shouldn't everything be documented better, for our end users?'

My advice to you is don't be that guy.

Some day, you'll be a kick-butt senior level guy who is hired and paid to make those decisions. When that day comes, go to it! Until that day, realize what your position is. I have a boss, as far as I'm concerned my entire job is to make my boss happy. It's not to second guess decisions made outside of my pay-grade. If you really aren't sure, talk to your boss/supervisor and find out.

Generally speaking though, it's far better to have everyone on-board with an outdated approach than half the team following the outdated approach, 1/4th of the team following some new approach and 1/4th of the team trying to develop a cutting-edge, brand-new approach.
