So many ways to communicate....

I was talking to my sister the other day and then my mom, and started thinking about how easy it is to communicate. Way back in the day, you had a messenger on horse back. Then the evolutions of: telegraph, mail, telephone, email, pager, cell phone, email mailing lists, forums, text messaging, and live video over a computer. The only thing that's left is being able to beam yourself somewhere like in Star Trek.
