Wish, which is a Pinterest-like e-commerce site, had a burst of more than 1 million users between Wednesday and today. The site seems to have begun some sort of promotion, though it’s too early to see whether the app will continue to grow or how many of those new users will return.

No. 3 on the list was Terra, a Spanish-language web portal, which has integrated Facebook Open Graph. Other social readers appear to be making a comeback after a drop-off in the past few weeks. Facebook continues to experiment with how it displays Open Graph app stories in News Feed, which can have an effect on an app’s monthly and daily active users. Washington Post Social Reader had a 330,000 increase in DAU, and The Guardian picked up 260,000 DAU.

Mobile video sharing app Viddy had a spike in DAU on Sunday and Tuesday, after Justin Bieber tweeted links to some of his Viddy videos, including one of him singing with his little sister and another of a live performance of his new single.

At No. 11 was Song Pop, a song guessing game for Facebook canvas, iOS and Android, which is on the rise since being added to Facebook’s App Center with prominent placement rotating in the header.
