The email address? There's no reason they should IMHO. At this point Aol email really has to be one of the longest lived and most stable services out there, and it's weird to even type that :)

The ISP? They could be paying less for a faster connection, and a new ISP would probably throw in a better wireless router than the ancient one they're using (and occasionally having trouble with).

The two are not related - AOL is a free online portal these days, accessible to anyone using any ISP. You can even go there and sign up for free email right now if you want. I can imagine a 'retro' email address fad might hit at some point ...

Looks like my email address from 1985-1993 is taken. I wonder if at some time it got recycled for lack of use, or if it's still me, but I have no way of logging in to QuantumLink or the old AOL service.

[e-mail] appears to be available though :)

I have no idea if they recycled any addresses, I used to know someone that worked for them about 20 years ago, but she was non-technical and probably wouldn't have access to that info back then. And 20 years ago AOL were already considered outdated and uncool!
