I like that you can have your whole team in one place while still being able of working separately if needed without having everyone at their desks all day.
Also it's great how easy it was for me as an intern/student who had never used this software before just signing up (no tutorials) into using my colleagues computer remotely so i could continue work when they were offline! It took some time getting use too but once we did things got much easier using remote access over VPN or even through Google Hangouts from another country than local network IP addresses!! We are mainly doing SEO tasks such us creating blogs posts etc which takes quite long hours sometimes days depending what task its trying do be completed. Having everything together makes collaboration very simple since no matter where people may currently live around world there would always be someone online available 24x7 helping out other members within our teams.
