The word ‘hipster’ is used too frequently and oftentimes incorrectly. This is one of the times, though, that we’re not mad about its use.
Some absolute legend has created a Tumblr called Hasid or Hipster.
It’s basically just a blog roll of photos of dudes with beards (and, interestingly, often spectacles) who appear to be either Jewish or hairy cool kids.
Some of them are easy guesses – for instance we’re pretty sure that the image of the Rabbi is a no brainer – but others are pretty tricky.
The only flaw of this whole site is that we never get the answer, so your guess is as good as ours.
