Increasingly the expired button seems to be used without just cause, and more often than not - especially on the rare deals - as a way to put others off the scent.
I've not really thought the following through, I was just aimlessly staring out of the office window when it came to me.
Put simply, any deal over a few weeks is USUALLY expired. That doesn't include vouchers etc, but then they shouldn't be in deals anyway.
So how about a mixture of the expired system crossed with those work/don't work things you see on those god awful voucher code sites.
Basically you can no longer expire a deal - you can only say a deal is valid. A deal needs a certain number of 'valid' clicks per hour/day/week for it to remain active, and once that deal fails to meet the target of votes, it becomes expired. Deals can also be 'unexpired' by users - once the deal hits a 'comeback' target of valid votes. ie: The valid button is always available, expired or not. Users get 1 click of the valid button per set period.
All the targets can be adjusted depending on time of year/hits to the site etc, and the mods can still override items individually.
Any thoughts or shall I get some work done instead?
