So this is essentially a 1-1 chat app that connects an &quot;expert in any desired field&quot;. Self-described as &quot;real-time wikipedia&quot;.<p>One thing I find annoying right off the bat is that this is an app only: there&#x27;s no web version.<p>If you did want to actually spend your time answering questions, you&#x27;d be forced to do it on your phone instead of something with a full keyboard, screen real-estate and multi-tasking.<p>I&#x27;m not sure how they find experts (seems like they&#x27;d just be normal users who happen to get high ratings), but I wonder how they plan to prevent burn-out?<p>I know I am not alone in hating answering the same questions over and over. I actually make a very conscious effort at work to answer questions people ask me by updating our documentation (tickets, wiki pages or source) whenever I possibly can, even if they send a 1-1 chat message. It takes more time than answering directly, but it takes less time than providing that same answer a second time.<p>In fact, you see on communities like StackOverflow that some people seem to almost delight in closing questions after they&#x27;ve hunted down the duplicate.<p>So that seems to me to be a big barrier to sustainability. Enough user volume and churn is probably the only way to combat this -- keep bringing in fresh people willing to answer the same questions -- but that can only go so far.
