Facebook (FB -1.3%) roundup: 1) Macquarie isn't scared to upgrade shares to Buy ahead of a 234M-share lockup expiration: the firm thinks the huge gap between mobile's share of ad spend and media usage is a big opportunity. 2) Facebook has shut down a test of its Pinterest-like Collections feature, which some hoped would become a way to monetize e-commerce. 3) Facebook is hoping game quality improvements will help reverse a decline in gaming activity (and thus Payments revenue) - is that an opportunity or a challenge for Zynga? Update: TechCrunch now reports Facebook will nonetheless launch Collections on both its PC and mobile platforms.
