* Short-term: Active users won't delete their accounts because the benefit they get from Facebook outweighs their annoyance at the privacy issues. Long-term: Once a viable competitor comes, active users will change.

* Short-term: Revised privacy controls ease the pain. Long-term: Permanent brand damage has happened. No longer can we believe in the sincerity of Facebook's "oops, we made a mistake" since it's becoming a pattern for them to ask forgiveness rather than permission. Remember Beacon? It will take years for the "we don't care about users" branding of Facebook to go away, if ever.
