There is a strong commitment by the community to prevent the site becoming like digg, reddit, or slashdot. Losing focus on the topics that brought us here in the first place (technology, startup culture, and programming) is the first step on that path in my opinion.
All I can ask is please, try not to submit/vote up stories which are not particularly related to tech. It's not what I'm interested in discussing in this particular venue.
Or maybe I'm just in the minority. I guess time will tell.
P.S. Just because you put the word "Hacker" in your article/title, doesn't mean it belongs here.
Which itself is a problem because the threshold is so low. By even the most conservative estimates there are thousands of people visiting the site every day yet it only takes a handful or so to get an item to the front page.
So even if 99.5% of the people here make a "strong commitment" as you put it the front page will still be flooded with all those TSA stories
As you say, currently there's no way to say "there's nothing interesting on the front page" even if a majority think that.
