Facebook is rolling out its new Timeline format to brand pages, but the flashy visual template adds too little style while removing too much substance.

First, the good part. Some news organizations have used the Timeline format to assemble interesting chronologies of themselves and their reporting.

The New York Times tells its 160-year history with a Timeline documenting the evolution of the newspaper and those who worked there.

The first entry of the New York Times' Facebook Timeline is its founding in 1851.

NBC's Meet The Press filled out a timeline dating back to its 1947 founding, with images of guests and moderators appearing on the show through the years.

A section of the Meet The Press Timeline from the 1950s shows appearances by Robert F. Kennedy and Jackie Robinson.

While this is interesting, it seems to be of little enduring value. I can imagine spending an hour one Saturday afternoon poring over this history of the New York Times. I can't imagine going back to it regularly.

Meanwhile, the Timeline format mucks up the things that Facebook Pages actually need to do well.

The most important function of a Facebook Page is to greet new visitors and convert them into fans.

The Los Angeles Times Facebook Page greets new visitors with a Welcome tab inviting them to like the Page.

With the Timeline format you lose the ability of traditional Facebook Pages to designate a custom "tab" to welcome new visitors. Timeline-style pages always load the Timeline by default when a user visits.

Timeline pages also are significantly slower to load and make it harder for the user to do the most fundamental task -- quickly scan recent posts.

Certainly Facebook will continue to improve on the Timeline format, so maybe in the future it will develop more advantages. Facebook has said the new format will be applied to all Pages by March 30. For now, most news organizations would do best to stick with the old format as long as they can.
