You can keep up with your friends on almost every level with popular social networking sites like Twitter, Instagram and Facebook. If your friends go camping, fishing or whatever, you can see what's going on. But what if you wanna see a complete stranger's weekend? It's simple, just do a search for a keyword and the "hashtag" will come up.

But do we really give a crap about anyone's hashtag? They only time I hashtag is when I really want someone else to see. What I do is pretty much not anyone else's business. HA!

That's how I feel, but check this video out from Jimmy Fallon and Justin Timberlake. It has over 20 million views.

They got it right and funny on top of that. #OMG #Checkitout and #Hashtag #Myhashtag ! #BOOM
