Amongst the people I follow on Twitter, this π has π become π a π way π of π emphasizing π one's π point.
I think it's hilarious. But when I tried writing like that, copy-pasting the π emoji quickly got annoying. So I made this: http://shivankaul.com/emphasize
Just type in a normal sentence, and press Enter.
Now if I could just make a similar tool for empathy, the internets would be bearable.
