How do you use the internet?

I know this sounds stupid, but I've forgotten how to use the internet, as well as what I used to do online other than here, FB, Utube, amd some other things. But by and large I know there's a metric fxckton of things that I forget what I used to do.

So here's my question: how do you internet, reader of this thread? Maybe your input will help me in my amnesia.
