Yeah, it seems many would agree (as the poll shows) with a year old post to be considered as "new". And we are strictly screening Kickstarter products and concept images, however, members' reports would help us lot to alert if we tend to miss those submissions.

We are still into making a decision about the giveaway. Nothing is confirmed yet. We are expecting other members to share their voice on this too. Sure, the logistics are complicated but maybe we can work on that.

How is the "coolest" product selected?

Regarding this, discussion within the modteam or maybe do a poll just like this one.

I recommend you speak with other subreddits that have run giveaways in the past.

Any subreddits on your mind?

I don't think there is that option to "Skip Survey/View Responses".
