We all have our personal, inner conception or mental map of the Internet: which are the important places, where can you find what you are looking for, what are people doing when using the web and so on.
It is safe to say that each of us has a false image – or at least a very far from complete image. We are guided by habit, hazard and home: you are socialized IRL into the understanding and inner image you have of what there is and what is going on – on the world wide web.
Let’s stop for a minute and rethink this. Imagine you heard about the WWW for the first time just now. Someone tells you that it is a network that thousands of millions of people fill with text, images and video 24-7. And searching that content works pretty good thanks to various tools at hand.
If you were to take in that information and assess the possibilities offered by such a source, would you then not want to get a birds-eye view of where the users are hanging out? Which parts of this network that see a lot of activity, that get a lot of attention from the users? Think of it like looking up the number of book volumes in the different topic departments of a library – it is useful to know where there are a lot of sources, and where there are fewer.
Whether you agree or not, here is where you can check out which the top 100, top 1000 and top 1 000 000 websites are based on number of visitors during a month (visitors from the United States):

As the numbers will tell you, the top 3 sites generate on average 10 times more visitors than sites ranked 101-103, which gives a hint that the distribution of visitors follow a Power Law curve:

One point to consider is also that there is a world outside of the United States, which means that the list would likely change considerably if internet users in India and China were also measured.
So, where people are going when using the Internet is one thing – but there is more. Royal Pingdom tells you how many the user are, how much content they consume, how much content they create etc etc…
