Answer to Question 2
Answer: Email has been an important communication tool for many companies for several decades, and in the beginning it offered a huge advantage in speed and efficiency over the media it frequently replaced (printed and faxed messages). In addition to the widespread availability of better alternatives for many communication purposes, the indiscriminate use of email has lowered its appeal in the eyes of many professionals. In a sense, email is too easy to useit's too easy to send low-value messages to multiple recipients and to trigger long message chains that become impossible to follow as people chime in along the way. In fact, frustration with email is so high in some companies that managers are making changes to reduce or even eliminate its use for internal communication.
However, email still has compelling advantages that will keep it in steady use in many companies. First, email is universal. Anybody with an email address can reach anybody else with an email address, no matter which systems the senders and receivers are on. Second, email is still the best medium for many private, short- to medium-length messages, particularly when the exchange is limited to two people. Unlike with microblogs or IM, for instance, midsize messages are easy to compose and easy to read on email. Third, email's non-instantaneous nature is an advantage when used properly. Email lets senders compose substantial messages in private and on their own schedule, and it lets recipients read those messages at their leisure.
