I don't think BuddyPress will be something you use instead of your existing social networks... but if you wanted to start something new maybe with more control, friendlier terms of service, or just something customized and tweaked to fit exactly into your existing site, then BuddyPress is a great framework to use.

I think that all services will have downtime. No matter how much you prepare, have redundant systems, or audit, there will periodically be a black swan event that is completely unlike whatever you've experienced before. It even happens to Google!

If you still use 'admin' as a username on your blog, change it.
