"Is it just me or is there a trend of reactionary posts (or just submissions?) on the same topic? A few days ago it was Go (why Go is awesome, why I'll never use Go, why Go has its pros and cons) and now it's college's turn."

it's not just you. it's a signal/noise problem. I read HN through a filter site I made and I've thought about clustering these types of stories on my filter site, because I don't think they really deserve separate billing. it's kind of like the site wants to have trees of links, instead of one flat list.

anyway, the reason I call it a signal/noise problem (and of course this is just my opinion) is because often the reactionary posts feature very, very unimpressive reading, and are really only there to serve as a focal point for discussion, or maybe to serve as something to upvote, for people who disagreed with whatever the story is reacting to.
