Whenever you do a search for something and find a relevant article, before you invent too much time into reading the information, take a look at the “written on” or “last updated” date. This way you can know how new the information is.

Of course, a lot of information doesn’t change and the date won’t matter, but it does matter on some topics. For example if you are searching for an article on computer security, the newer the date, the better.

Just something to keep in mind.
