Call me a square one if you will, but it’s not impossible for nerds to be cool
There are two big spaces that I fit in, and it is rare that I fit in both
I fit the best in spaced, but that wasn’t for too long
And when I was round, I did my best to fit then, too
Though it is not my shape, I do have a fondness for cones
Who am I?
There is at least one clue to this person/thing in each line, but list any that you think apply.
