What's the deal with "Mark as Installed"

[Meestor_X]

I had a feeling after I posted this question that it might be met with some hostility. I tried to word things in a way to be just a casual question, but as often is the case, my intent was mistaken. Seeing the responses though, it is clear that this button is of great importance to the coders as I already knew.

Just to be clear, I wasn't suggesting anyone NOT click the button or that the button wasn't a good idea, especially for the person clicking it (updates and so on).

I was just curious why the coder himself would care. I'm a programmer, and it's only of passing interest to me whether or not anyone uses my FREE programs. (My paid-for programs of course I feel very strongly about) I write them because I needed them for myself and then post them to the world in case someone else finds them useful. Doesn't really matter whether or not they do. Seems to not be the case here.

It's certainly not the first time though that what I felt wasn't important to me was of great importance to others, but I was curious, that's all.

As I said, I'm just curious as to what the coders get out of it to inspire such passion about whether or not the button gets clicked.

Sorry to raise the hackles on everyone.
