I guess I'm just frustrated that the current structure of web has created all sorts of malincentives around the exchange of knowledge. Trollish content attracts more attention, so well-meaning creators of worthwhile content are incentivized to wrap legitimate ideas in trollish presentation in order to reach a larger audience.
I wish this weren't the case. I hope it changes in the future.
That's the same problem that TV and radio "news" has had for a long time. I don't think the problem has to do with the structure of the web. I think the problem has to do with human beings. And given that this keeps repeating itself, I wouldn't call it a "problem," more just "reality." I agree it sucks though, but presumably the low cost of spreading information on the web will allow niche information sources to flourish. HN itself is an example of getting closer to that.
