I'm not a particularly old member here by any means, but it's become very obvious that this community is too large for the current constraints on it. Minor changes, like implementing a separate area for political discussions would act as a sort of "release valve" without sucking up precious real estate on the front page.
My reasoning is as follows: there's no stopping wave stories like the NSA scandal from being submitted to Hacker News, people are too invested in hearing about it. Besides, there's some justification for it, being that it has a technical basis despite being political.
Moreover, it would lessen the impact to the front page for polito-technical debate to have its own "arena" of sorts. I would also motion for these to have separate karma/upvote/"staying power" treatment, similar to Ask HN: threads.
This way, the top stories or homepage will have more diversity and content.
