I love it that is easy to use,it saves me time when communicating between colleagues within my office as well across different offices in Australia & New Zealand using our Google Apps accounts (mailing lists etc). There are no major dislikes but if there was an option for multiple groups/subscribers would be great - maybe some type where we could assign certain roles like'read only' access? Great product overall though very helpful at keeping all communication channels open whilst having privacy levels set appropriately too.
