As expected, Facebook is porting its Timelines feature from personal profiles to brand (and band) Pages on the social network. It’s available now, but within 30 days all Pages will have to switch to the new, more visual design. “The goal is to make Pages more engaging and more social,” Facebook’s Gokul Rajaram tells Mashable. On one level, the changes are good for music artists, whose history of posting videos and photos will make for attractive-looking Timelines. Page owners can pin specific posts to the top of their Timeline for up to seven days, to keep a particular item or campaign to the fore. However, one feature that Timeline for Pages kills is the ability to use specific Page tabs as a landing point for fans visiting a Page – something that artists have been doing a lot. What does this mean for startups like RootMusic, whose BandPage app has been used by lots of artists? “Timeline creates a lot of new opportunities for BandPage,” says the company, promising new features to take advantage of it. RootMusic also has a quick guide to the new features, and how they’ll affect artists.
