Why do people tag the year on articles? I feel like hackers cling to the “if it’s not new, it’s not worthy” paradigm. Update: Thanks for all the replies, makes sense. Why downvote an honest question?
I'd say typically in software, once something is beyond about 5 years old - a library, a resource, a language version - it's very important to be aware of that as your decision to use that thing as-is needs to take that into consideration.
Maybe you decide to use it, maybe not, but you're always better off knowing when it was produced going in than not paying attention to that.
