email takes longer bc u have to open read, respond, and continue . . . with instant messaging its fast and easy and u can also save the conversations just like an email

E-mailing is like sending a letter to someone. You can e-mail someone anytime. You can only instant message someone when they are online at the same time as you are. You can have better conversation with someone using instant messaging and it is a much quicker way to talk to someone online.
