The family photo market is enormous, and if my family is any measure a lot of people still use shutterfly and other print-oriented services. It'll be interesting to watch over the next few years as more and more grandma's start getting iPhones what happens

Welcome, @mulligan! Love that your sharing your process openly. I'd love to see more startups do this. Looking forward to seeing the next release. :)

Mosayc (http://www.getmosayc.com/) just released. Has similarities to Cluster but marketed toward a younger audience.

I played with Cluster after it first launched and didn't find a need for it although I can see my mom really digging it. She's a photo nut, often creating physical albums and framing her photography but Facebook and Instagram lack the personal interaction of sharing an album with close friends and family. I'll have to try it out again but I'm curious how it overlaps with Heyday and Memoire.

My parents are in town for the weekend. Perfect time to try it out. :)

I may be completely wrong here, but I feel like the more tech-savvy that grandma and grandpa get (I have kids, so there's some understanding here), the more transient photos become. The less we need to put them in albums, b/c grandparents will have way more access to way more content. It's easier to produce the content, easier to send, easier to digest/consume -- do we really need albums? We still print photos or put them into small albums when we want to give my parents or grandparents (so great-grandparents) gifts...but even that's waning. Now I just take a photo or video and Instagram it, where my dad hangs out, or screw it, just send via email and then get email responses back that I share with the kids.

Try the product. I think the comments here are right. But this product is different. Easiest way to collect photos from several ppl in same place and view all together

Thanks all .. Just joined the community, so first time seeing this. Cluster has been a fun project to work on. Over the past 6 months we've seen people utilize it more as a communication tool with a private small group and less as a photo bucket for post event aggregation. Doing a lot of user testing around that now (posts on how we're doing that at https://medium.com/cluster-ideas). Causing us to make some big changes to onboarding / education. New release out soon to add some of that for new users.
