I hated when someone posted in a question of mine dat was like 1-2 years old... but hey dat's too far... one month's good I think...
I'm kind of surprised at the 180 degree turn from them.
In the past, I expressed frustration at the opposite - that you'd answer questions and be thrown at a list of 5 month old similar questions, which showed a total lack of awareness of how users actually use the site, which is not using the useless search, but instead sitting on action on the live feeds.
So now they've gotten that. But they got it so much, they went too far. The 24 hour cutoff seems a ittle short to me, i'd rather have seen a few days worth. But the 'close as soon as best answer' is a huge fail.
To be honest, I'd get rid of most helpful' altogether.
They seem to think the point of the site is to ask a question and get 'the' answer. All the interesting questions don't have 'the' answer they have a range of views, and the range and discussion they generate is what's interesting.
The point of the change is to increase action on the live questions, but they're actually suppressing it by trying to end questions that are still being discussed.
