Expect big things from this location-based service.
Brooklyn-based Hot Potato launched a site and iPhone app today that lets groups of people share and create streams of content around events.
You can create an event like a concert or a football watching session and let other people check in to it. Everyone “checked in” at an event can post their thoughts, photos and videos about what’s going on, creating a stream of activity for others to see.
All the content is curated by “likes” and “comments”, so Hot Potato can surface the most engaging posts. You can also specify that you’re “attending”, “watching” or “following” an event someone else has created like a concert.
You can look at people’s profiles and scroll through their stream of activity. Hot Potato uses Facebook Connect for log-ins, so you can pull in your existing friends. The company is backed by Vimeo co-founder Zach Klein and launched at the Real-Time Crunchup in San Francisco today.
