With the new technologies & trends right now, how do you convince yourself not to ride the HYPE train or the bandwagon?

* I have friends from different companies who talked to me about their stack, like "We're using INSERT_JS_FRAMEWORK_OR_LIBRARY_HERE ... It's very cool."

A simple advice or a thought would do.

To figure out if it is actually usable, try building a small side project (even and old one of yours would do) using it. At the end of the day, it's you who should decide if it's amazing or not.

Also a good rule of thumb is the size of the community and support. I use a framework which is a month old I think, and I have to go to issues tab on GitHub if I encounter any problem, and even then there's a bleak chance i would get something satisfactory.
