Social media news round up

Just a few news stories that have recently come to light:

Flipboard is being launched for the iPhone in the Apple App Store later today. This has been a very popular app on the iPad for looking at various social media feeds and popular websites.

Facebook Timelines is beginning to rollout after testing. New Zealand will be the first country to see its features.

Geolocation app Foursquare now has 15 million users. Whilst it continues to grow, this is still a low penetration of smartphone users. With Facebook's recent purchase of Gowalla (seemingly a talent grab) the future of geolocation marketing looks like it will be dominated by Facebook Places.
