I've only recently been introduced to Twitter, and I found the user experience around threaded conversations lacking: top-level replies are easily accessible, but deeper conversations are hidden behind Show Replies.<p>To that end, I've built Thread Tree over the last few days on the model of Thread Reader, where one requests an unroll by replying to the thread while mentioning the app bot. What I've got so far is an MVP, so suggestions are welcome regarding design of the interface, feature set, other opportunities in the space and so forth.
