What are the benefits of using those sites?
I’ve heard Yahoo! is good for stock market trading and financial news, but haven’t heard anything else about any of them.
I’ve had my Hotmail account since 1999 when I was in high school and it still works well enough. It’s what 99% of my accounts or web presence is tied to. I still occasionally get emails from old friends or forum members I haven’t heard from in years who only know me at that address.
I’ve spent (to me) a significant amount of time getting the folder structure, auto-sorting rules, and junk mail filters set up the way I like them. I just can’t be arsed to do that all over again for some new address that will also be considered uncool in a few years time.
I do have a couple more ‘professional’ emails, like first.last@respectableprovider.com, but they just forward to my Hotmail account anyway.
