Ruby and Ruby and Rails still feel fresh and new to me, but (surprise!) Ruby is over 20 years old, and Rails is nearly 12.

A lot's happened in the ecosystem over time, practices have changed, gems have shot up the charts and later fallen out of favor, and new programming techniques have come on the scene.

Keeping up with this can be a challenge, especially for those working on long-term projects and/or on stable teams with few newcomers: how do you get your job done and ship a product while also continually refining your skills and learning about new solutions & professional best practices?

You know there are twitterers, podcasts, courses, books, and even blogs (yes, people still do those!) - but how do you find them, and which are worthwhile to invest your time and money in?

Let's pool our knowledge and share!
