Talkshow
Given the number of message screenshots we see a day, it's obvious there are a lot of people who don't mind their conversations being public. Talkshow lets others follow your conversations in real time. To use it, simply start a "show", give it a name, invite your co-hosts from Facebook, Twitter, or your contacts, and start talking. Each show gets its own easily-sharable URL, and editors will be on the lookout for the best shows, boosting them to the front page of the app. You can also follow other shows, like individual messages, and even send reactions. No screenshots necessary.
