Facebook is rolling out Timeline to all of its users. You’ll remember that Facebook introduced Timeline at its developer conference as a revamp of users’ profile pages. It’s more customizable and keeps a record of lots more activities, including the auto-sharing apps also introduced then. At the time, Timeline got at least as much coverage as the other, more important platform features revealed. While Timeline looks cool, it requires a lot of work on the part of a user that wants to curate it, or customize views for different groups of friends. Probably too much work. (Ironically, Timeline for companies could be a slam dunk, but that’s not Facebook’s current plan.) And while Timeline is more or less synchronized with Facebook’s HTML5-driven mobile strategy, I expect the mobile experience around Timeline will need some adaptation. Regardless, it’s worth watching how users adopt this new profiles. Will Facebook make it easy enough to manage multiple, curated personae? Perhaps, but it doesn’t appear to be there yet.
