Lately, Yahoo has been nagging me to not use anything but their official apps and web interface to access my email. I guess this news is why.
Screw that. I pay $20/yr for SMS/IMAP access to my email there. That means I get to use Thunderbird and iOS Mail, and they get to keep their servers secure.
I use Yahoo mail regularly, mostly for job search and other official biz. I joined years ago and was able to get [firstname].[lastname]@yahoo.com for each member of my family when they started allowing the dot to be used left of the 'at.'
(For personal email and website registrations I use my earthlink address.)
