I read the new page rather than the "front" page, because so many interesting submissions never make it to the front. Likewise, there are so many duplicates that won't make it that ought to be flagged.
I'm getting tired of bothering. I rarely, rarely get any karma for this, there is no reward, and the problem is getting worse. I'm going to stop bothering soon, and write a Bayesian-based filter to auto-detect the things I might have an interest in.
The mechanisms here are failing to find things of interest to me any more.
Maybe the site should encourage those with higher karma to spend more time policing (the put up or shut up method).
