U.S. users are leaving Facebook by the millions, Edison Research says

What are people's thoughts on not deleting FB to better secure your personal identity. In the context of leaving google's services, I see people say that they sit on their email so no one else can take it, but I never see that sentiment about deleting fb.

Is it just that the bar to successfully impersonate someone via fb is higher and email is lot easier to manipulate?

I am particularly interested because I am planning on deleting my personal fb soon.

It's easy to not delete and stop using to serve your purpose. I loathe facebook et al., but some employers (fewer and fewer these days) want to see my online presence. To not have a facebook was considered strange, so for that reason, I keep it around. However, as far as maintaining an identity, or holding on to your custom facebook url, that’s a non-issue. Delete away, and create again—facebook is intelligent enough to reconnect you to all those people if need be. Personal identity is strengthened by other's endorsement. That's easy to get again with FB, especially if you're who you really are. It's difficult to take someone’s identity in that sense and it be valuable to the person doing it.
