Oh, there's definitely a silent majority when it comes to the internet. If I were to use my DeviantArt as an example (totally not shameless plugging), while there are people who favourite, comment, complain, and so forth, there is always a big amount of people in my watcher list who don't, but just look at my work, appreciate it by themselves, and move on.
This happens on every part of the internet. I'd know, because usually I am part of those people. Only venturing into YouTube comments in very rare cases is a given, though. :P
