No you shouldn't be concerned. Facebook for me personally, turned into just "blocking" everyone on my feed, because all they posted was garbage. It was endless posts of people airing their dirty laundry. Too much drama, so at the end of last year, I closed my account, and haven't logged in since. I do however have a separate developer account with zero connections, so I can get work done.

LinkedIn, I still have an active account. But I really don't "get it". The amount of garbage and spam posted by your connections on there, is quickly approaching Facebook levels. I rarely use it, except to clear out inbox requests from head hunters. It's basically a SpaceBook for business people.
