Pinterest today introduced a new search feature that's made with mobile phones and tablets in mind. It's built to be manipulated with swipes rather than typing, and it's based on open-ended discovery rather than finding specific things.
Of course, Pinterest's version of search is limited to what's already been posted on Pinterest.
But that's actually a whole lot of stuff. There are now 30 billion pins in Pinterest, with 750 million pinboards, and 100,000 retailers posting their products.
