Wouldn't say obsessed, but as a person who would, if able, list "the Internet" as country of origin, the show has been hard to miss for quite some time, and I gave it a watch to see what all the fuss was about. The show is funny and extremely memetic, the characters are more rounded than their initially stereotypical roles make them seem, and the show is much more entertaining than a 20 minute flash video for girls aged 4-11 has any business being. Seriously, this show has a character that is pretty much a cartoonified Q from Star Trek, voiced by same. And Slenderpony!
Basically, after watching Criminal Minds, Dexter, the Blacklist, the Mentalist, Breaking Bad and Game of Thrones, it can be nice to clear your head of all the gruesome and just watch some pastel ponies for a bit.
Also, by far the girliest thing about this show is the intro theme song.
