Another reason we meed collapsable threads here. You'll never stop "noise" entirely, but bullshit threads that sparked by OT comments could be easily snipped with collapsable threads.
I've been using the Hacker News Enhancement Suite[1] for a while in Chrome. Among RES-style features like keyboard navigation it also enables collapsable threads. The source[2] is available on GitHub.
