Yeah, lots of technologies out there.

Personally I consider learning a technology as an investment. And with my investments I prefer them to be low risk. That's why I only choose technologies which are definitely going to last a while. Sometimes it's hard to decide if a particular technology will persist. I usually look for support and endorsement of big players in the industry and sufficient user adoption.

Right now I am contemplating using angular.js. I think it would be low risk to learn since it will probably last a while because of Google's involvement and already wide usage.

Other safe options include Twitter Bootstrap, Node.js, Android and jQuery and ?

I would like to read a blog post about what Hacker News considers to be safe options to learn. Anyone interested in writing one?
