But with recent estimates putting the size of the internet at well more than 100 million distinct websites, it's getting harder and harder to get a handle on all the great stuff that's out there. That's why we've compiled this list. And unlike some lists you may have seen, which try to name the very "best" websites, but end up just telling you a lot of stuff you already know, we've chosen instead to highlight 50 of our favorite sites that fly under most people's radar. Think of it as the Maximum PC blog roll (remember those?).
