You mean you was 'oblivious' to it?
My online name has quite a long history. I used to run a FidoNet BBS; I called it "Oblivion and You" after a song called "You And Oblivion" by a musician called Robyn Hitchcock. (The latter's been doing stuff with Peter Buck of REM lately, but he tends to be regarded as obscure, sadly.)
Then I discovered a rollercoaster called Oblivion at a British theme park called Alton Towers. It trumpeted itself as the world's first vertical drop rollercoaster. (100 feet in freefall, effectively, and it holds you over the drop for just long enough for you to wish you'd never got onboard.)
So the BBS gained a subtitle. The world's first vertical drop BBS. Nonsense, of course, but as I never had more than a handful of users, nobody much cared.
When the BBS' hard disk died, I spent a while wondering whether it was worth resurrecting the machine, but reluctantly decided it was more work than it was worth. (I think it was one of the last handful of FidoNet nodes in the UK: it wasn't quite me turning out the lights as I left but I was pretty close).
So the name lives on, sort of. I still miss Fido...
The avatar is a shameless copy of the Oblivion (rollercoaster) logo that I built a small animation with, mostly because I wanted to see if I could. (A close inspection will reveal that my animation skills are not exactly brilliant, but I think it's probably okay for a beginner
(And modest too.)
My modesty, as you have clearly indicated, is just one of my fine attributes.
