Hello Mr. Fernandez,

[...] How's this for a good example. They have taken a bunch of related "niche" stuff and put it into a meaningful list. A good practice. This is a bit more art than science because it involves knowing what a group of people need at once. The niche stuff could include a variety of things from many different parts of the web. More often than not I would say these lists are specific to an application area for a specific group. Such as fiction writers (like me*cough*). [...]
