Well, kids tend to access a few sites only. I did when I was younger. I mean: What they need to do on a browser?

Facebook? Wikipedia for school? Hulu? I guess kids needs are more easily found, they need to remember a few sites that cover a big percent of their total usage.

I mean, it's not like they have to make some _hard_ research on topics they are interested due to work or hobbies.

I think you nailed it. The sites they tend to visit are VERY important to them. Do you remember being a kid? The video game you were playing or movie you watched last night had the higher priority in your life. You don't have to think about too much.

As an adult, you have an amazing branching tree of knowledge and interests. You have to track so much information that everything has to become less important.
