Ask HN: Need the name of a social network, or social network like website

I'm trying to remember the name of this social network/website. I read an article at work the past few days that featured a number of screen shots from a social network. I remember the article said that it's design was so good that apple should buy it just based on the design.

One feature (from the screenshot) I remember is that you can post an update by drawing on it, besides a number of other possible update types.

Please help HN
