So smart!

i like the fact you can share vids to show epic moments like when streamer do something awkward (be aware!)

also smart by Twitch yea they need bigger servers and properly pay a good load of money to keep them running not to mention the storage (how ever that works)

but it will be A LOT of ppl sharing and making free links for twitch 
well done commercial ppl in twitch well done!
