There was this thread - https://news.ycombinator.com/item?id=9334927 of people's stashed domains mostly because of hoping to see it live one day, but left out due to many cases..

So, If any of you are willing to give-away or exchange domains with different TLDs we can do it here.,

myself, I have codebetter.co and I would be happy to giveaway if anyone's interested..
