Yet again, you have discovered the most amazing video. You've never seen it before, but omfg, IT'S AMAZING.

And as the calculus of the web has taught you, time and time again, amazing = sharable.

Your friends will love this video.

You are a master of discovery, they will say. You are a cultural connoisseur, a curator of viral video delight.

But wait.

You usually trust your instincts, and you rarely pause for reflection, but today, for the first time, you wonder, should I really share this with my friends?

This is a complex question. But it is a solvable dilemma. This how-to guide will help you solve this quandary. You just need to ask yourself a few quick questions….

First, look at the view count. In prominent 19-point type, YouTube tells you how many people have seen the video. If it has over 10,000 views, you should think twice about sharing this video with your friends. If it's over a million, you should only share it with your cousins back home.

Next, look at the date. Was the video created today? Yesterday? This week? If it's any longer than that, you should certainly not share this video.

Now check out the comments. Has someone already composed a witty rejoinder more clever than the witty rejoinder you had planned to share with friends? That's not good. Being clever is crucial to sharability, so you should reconsider sharing this video with your friends.

We're almost done. But take a quick glance at the Likes. Is there a high proportion of Likes to Dislikes on this video? If the masses seem to dislike it, then you probably should not share this video. (Unless of course it's Rebecca Black. Haha, it's funny to share bad things!)

You've made it this far, but you have one more step. Do a quick Google search. Has Gawker Media already written about this video? How about BuzzFeed? HuffPo? Break? If the answer to any of these is yes, you should not share this video with your friends.

In conclusion, you should probably not share the above music video where five people play guitar simultaneously. Unless you're the kind of person who likes to break all the rules.
