For a programmer, finding information is important. Not just finding information about code, such as while debugging, but finding information in general.
Suppose you need to write a client which talks to a server with sockets, but you don’t know how sockets work in your programming language of choice. This is something quite typical, and even if you’ve been programming a language for a long time, it’s possible that you forget things. I have problems remembering the order of parameters for some rarely used PHP functions, for example. Not to mention various libraries that you may encounter.
Finding information on the internet ought to be easy, right? We have Google, and using Google is as easy as keying in a search word… right?
