How many times have you been stuck on a "reply to all" document/comment binge? This tool, combined with something like Draft (cc: @natekontny, perhaps Draft already does this ;) would be a great boon to the "send me your updates in a special named version" method of document sharing. @rrhoover
@grmeyer thanks for sharing! This looks very similar to Dispatch which shut down after being acquired by Meetup (http://techcrunch.com/2013/10/09/meetup-com-makes-its-first-acquisition-with-dispatch-will-roll-out-improved-messaging-communications-in-early-2014/). I used it to collaborate with the Startup Edition contributors. EXCELLENT tool.
