I remember Gmail invites. Ironically, Evan Williams (formerly of Twitter, now of Medium, at the time working at Google after they bought Blogger) was the person who sent me mine—and on the morning of April 1st, 2004. So I've had a Gmail account since the first day it was publicly available.

Yes, had one from an uncle.

I then realised that I could invite a second account, so I created a handful of accounts and still own them today.

Good times.

I actually got an invite from Google because I was on blogger.com back then (sad to admit it...)

I probably could have picked [email protected] were it not for the 6 letter minimum, so ended up with [email protected] which still yields an absurd amount of messages meant to a variety of other recipients...

Sure, I bought one off ebay for 0.10€ :D
