Oh, and I've said this before: Hotmail. Hotmail was great, because in the days of dial-up and land lines, you'd get your e-mail address from your ISP. So every time you moved you changed your ISP (and phone number) (That sounds so surreal after close to a generation with cell phones and broadband.) Anyway, they Hotmail came along and it was great. You had a permanent e-mail address. You could link it to Outlook or Thunderbird for a mail client interface or you could just use the Web-based interface. Then Microsoft bought to take out the competition it was giving its own products--and proceeded to enshitify it. Eventually they started calling it "Outlook" and even changed the URL. So I still have a @hotmail address, but it is now on outlook.com (or whatever the URL is).
The other funny thing: You know how, sometimes you remember something being really really good and then you get to experience it and are shocked by how shitty it turns out it was--it was just better than anything else you'd used at the time? Once I wondered if maybe Hotmail was like that, so I Googled screencaps of the old interface and I was wrong. 1998 Hotmail was fucking amazing. No ads and all the features something like Outlook or Thunderbird had. It was basically Outlook Web Access for free.
