101 Most Useful Websites

It is quite odd how we make lists, isn't it?

I often wonder why we have a Top Ten or Top Five or even a Top Hundred.

Recently I read Amanda's Top 26 Favorite Books of All Time.

Why 26 - well this author, writing teacher explained - there are 26 letters of the alphabet!

OK, so I guess that's as good a reason as any to decide on a specific number, but where does the hundred plus one come from? Why 101 most Useful Websites?

It is indeed a very useful article and pretty interesting too but why not 100 most useful websites or 99?
