Dear DN ,
I'm aware of feature requests page, but I thought this is important and decided to post it here.
The community is growing fast. You can observe this with 1. Sometimes new posts can't reach front page, they diminish on the second page without people reading it 2. Lifetime of a MOTD
I'll talk about MOTD as we can't do much for the first one.People are misusing it, advertising, writing childish sentences. Yesterday, MOTD changed 4 times (maybe 5) which is much. Because it is the motto of the day not the hour. Even though there is a silly sentence, it must stay there and people should see it and vote it. If someone typed something sucks, he should be penalized by down-voting.
Here is my humble solution: If someone updates MOTD, it must be locked for (let's say) 12 hours. No one can change in this time period. It will stay there at least 12 hours. ?f it's something nice he will get more karma, otherwise he'll bleed more karma.
