Which Email Service UR USing and Why

I`m using just yahoo because on this site there are the most people, and i think that the main reason it`s the messenger, for a while on the site too, and that it`s a big step forward, because nomatter if we`ll go to another computer, we will be on messenger without instaling a specific program. I`m using yahoo since i was young. It has a friendly skin and it`s always updated with cool gadgets.
