I actually think this stock can do very well in the medium to long term but I predict a bumpy road in the short term especially for those buying on a 20-30% spike off this Ann. Investors need to go into these investments with their eyes wide open - the time taken to generate meaningful revenues off these types of Apps is longer than you think and new competition - perhaps funded by likes of Google, FB etc - probably won't be far away so these guys need to hit it hard and they obviously can't afford too many mistakes if they are to keep the competition at bay...
