It depends on the intent of the advice.

If the advice is intended to let you "win the game", or "get ahead of the competition", then yes. If everyone is doing the same thing, then using it isn't going to provide you with any particular advantage over anyone else. "Add these words to get to the top of Google results" is doomed to eventual failure.

If the advice is intended to help you improve your quality of life, or improve at something specifically for the joy of being better at it, then being well known will not dilute it. "If you're feeling sick, then you should drink more water and rest" is just as valid now as it was when it was a new and revolutionary insight.
