What social media site do you use most and why?

Will chose best answer on the best explanation and certainty (no e.g Facebook or twitter)

I would have to say Facebook. As much as I hardly use it anymore, I tend to visit it frequently out of habit. Considering "everybody" is on it, it's easy to access information and details about people I wouldn't normally see on a day-to-day basis. When I don't have anywhere else to go, I type it into my browser and scroll through my news feed to catch up on other people's lives, see what they're up to or to send a message to someone I don't have a phone number for.
