Timelines have taken a backseat (just for now) to Geni.com. I have a family tree there I'm enjoying adding information and pictures to.
Geni.com is kind of a genealogy-based Facebook. Along with adding family history information, you can leave messages for family members - of any nature, not just genealogical - and collaborate, share pictures, and that kind of thing. And, like Facebook, it's as private as you make it, requiring an email address and password to sign in.
I would definitely recommend using this website and inviting family members to join (or joining, if you've already been invited).
