Reply All
I'm getting tired of Reply All. Think about this example for a minute. Suppose I send email to a list of 20 people or so telling them to let me know if they want me to send them something. Do you really think that sending a reply to the whole list of people is a good idea? None of them can send it to you so why do they care that you want it? What good does it do? Why not just send the reply to me? Now I know that sometimes a mailing list sets itself as the return address. But really how much work does it take to change the send to address?
There is a time for Reply All and a time to reply to an individual. Just think how much time and bandwidth we'd save if people gave a little thought before they replied?
