Pinterest, the startup behind the eponymous app that lets users pin photos and other content to boards, is announcing today the launch of a new feature in pins that lets users specify whether they’ve tried what’s shown in a pin — for example, a pair of running shoes, or a recipe — and optionally tell other users if they loved it or if it’s not for them. They can also post tips that other users can see later.

The feature is rolling out now on Android and iOS, and it will be coming to the web in the next few weeks, Pinterest engineering manager Nadine Harik wrote in a blog post.

“When you find a Pin you want to try, you can view a new feed to see who’s already cooked that recipe, bought that product or made that project and how it went for them. You can also see the percentage of Pinners who recommend the Pin,” Harik wrote.

Also, when you go to your profile on Pinterest for Android and iOS, you’ll be able to see all of the pins that you’ve tried so far.

This is a nifty, unconventional sort of addition that goes beyond the typical social network habits of liking, commenting, and sharing — sort of like how Pinterest has pushed into ecommerce through buyable pins.

The new feature could well make Pinterest feel a little less like a place where you find things you aspire to buy and a little more like a community where people help one another.

Last month Pinterest said it has more than 150 million monthly active users.
