I am an object,
But why aren't I the object of your affections?
I have over 50 brothers and sisters.
Each with a home to call their own.
Yet you need do nothing to get me,
Still, none here have me.
What am I?
Hint 1:
I am (at least in one sense), specific to the S.E. community.
Hint 2:
My, my, you guys are slack.
Trust the Math.SE to have my back!
