It is very easy to use for team collaboration with others that are working remotely or have different time zones - I love being able check documents from home without having my laptop next me all day! There's nothing at this point since it took us years of developing our product before launching out into public beta testing; however we plan on adding more features after launch date soon so stay tuned.
If you're looking for an intuitive tool where everyone can contribute as much quality work together then definitely consider using oworker while building products/services that need remote workers like myself :).
