"My ISP provides multiple email addresses for each customer. I don't understand why people would use anything else."
This works great until you change ISPs! I used to use my TWC address and then I changed to FIOS. Oh boy did I have a lot of work to do. I now use gmail and would recommend to anymore to never use their ISP address (unless as a juck email address.) Always use a generic service. Gmail is great for filtering spam. I very rarely get any that doesn't go into the spam folder.
