There are probably very good analysts out there, apart from @haejin. Of course he is not the only one, and of course, even his views are balanced, maybe his style differs from others. But what's the beauty of a community if there is no diversity?
I don't think calling people cockroach is a clever way to interact. If you have another point of view, please share, but don't blame someone just because he is doing good. Even you don't agree with him. Even if you think he is making too much money out of it.
Bring smart things on the table. People will follow your lead.
Bring insults, people will just ignore you.
