See, when you say things like, "Bloggers/vloggers aren't famous," and start writing that what they do doesn't "qualify" them for celebrity status, you really DO sound like you're telling everyone else that they can't find them celebrities, either.
Now, if you want to qualify that and say, "Me, I don't care for YouTube, don't watch it, and don't care who is on it, so I personally don't consider them celebrities." That's cool.
I have to assume you wouldn't consider a famous race car driver to be a celebrity either, if you didn't watch Formula One racing. Or a famous golfer. Or a famous politician. Or anyone else you never heard of before.
And, I'm assuming your statement "People often watch them because they are bad," is simply due to your obvious lack of familiarity with YouTube. No one watches the Tim Tracker because he's "bad". Quite the opposite. His little travelogues are among the most wholesome, wide-eyed, gosh-gee-whiz things I've ever seen. There's a LOT of excellent content on YouTube, far outweighing the bad. If you're not interested, that's fine. But writing off the entire medium simply because you heard or read a few bad things, is no different than announcing that "People often read novels because they are full of sex," just because you heard something scandalous about 50 Shades of Grey.
