Other’s call me a know-it-all, but I don’t know anything.

I can give information, but you will not know how much of it is true.

I can learn, but can easily lose my progress.

I have a bit of everything, but if I had to focus on one thing, you would lose me.

You may be wondering what my name is, dear reader.

I know you have heard it before.

The know-it-all who knows nothing at all is none other than the one you trust most: Google.
