seems odd because im only 19 but its not for me, just a waste of time uploading useless information and photos which become the property of facebook for eternity
I definitely understand your reasoning. Essentially, I use Facebook as a news hub. All the news sources that I enjoy reading have Facebook pages, so I have them "liked." For me, it's much more convenient than going to Google News and sifting through all the political crap in order to get to the science, tech, health and medical news that I actually care about.
As for friends, it's a nice instrument to keep in touch. But me for, it's merely an instrument of convenience.
