Is there a way to send the results of a search to someone via e-mail or post it on Facebook/Twitter? I'd love to be able to send an itinerary to my Mom for her to purchase (she foots Thanksgiving trips home) or be able to say "hey, everyone, these are the flights I'm considering taking to NYC/SXSW/whatever - what do you think before we all book?"
Back in the very early reddit days, Steve on at least one occasion waited for a user to request a certain feature via feedback and would push it a little while later. This of course gave the impression that he'd just put written that code for him :)
That said, it's nice to have the feature already there and just point someone to it.
