I tend to always ask this question because I always find it fun.

Why or how did everyone decide to choose their account name?

I choose mine because several years ago. I had to make an account for a game Spore) that I started playing. So I thought Explorer would be a cool account name. But at the time I didn't really know how to spell it and wasn't in the mood to look through the dictionary for it. So I just went with what I thought was how you spelled it, I typed out Expolar, and entered it. It took me a few weeks to realize I spelled it wrong, but I liked it enough that I decided to use it for most of my account names that I had to create.
