Facebook Camera App Launches for iOS (TechCrunch)
Facebook began rolling out a standalone photos app Thursday with which users can shoot, filter and share single or sets of photos and scroll through a feed of photos uploaded to Facebook by your friends.

This is not the first time investors in a hot tech company’s initial public offering have alleged that underwriters favored their regular clients at the expense of the little guys.
