This poem sums up the reason I rarely use Facebook. I don't know if this applies to you, but it very much applies to me.

Why I Don't Like Facebook, a short poem by UglyTurnip

Sometimes I scroll through my news feed

Only to see a status about weed.

I facepalm myself multiple times

When I see all my friends whine.

I frown, disturbed by someone I don't know

Why I added this stranger is a source of woe.

Some people on the site cannot spell.

The Grammer Nazi in me, I must quell.

So people of Facebook, can't you see

Why I have lost faith in humanity?
