I like how it allows me to be creative in my work, by giving input into what ideas they are trying out with their products! This helps make them better at delivering exactly as we need our apps designed for us - which makes everything run smoothly once implemented (and of course that's also great!). It takes time getting used too but all good things do :) The interface could look more professional looking if you have lots or users online/using your app every day than just those who use one offs here&there.. But this isn't much help now because there aren’t many people using any other platforms so its hard competing against eachother when most only know about facebook anyway!! So not really an issue anymore though haha.
