I've installed this app but haven't done anything with it. It wants to sync with my contacts, which makes me VERY nervous because of how much of a pain it was to get them cleaned up the first time. It also wants to connect with my linkedin profile. Will it start downloading and importing contacts? I don't want to just turn it loose until I know what it's going to do. Just curious from some feedback from people who both love it and hate it. It seems useful if everyone else is using it, but I have too many places where I already keep information updated. I don't think I want another... Thoughts?
