Now that that social media has become an unavoidable part of digital life, product designs need to adjust the way they approach their jobs. Facebook has put together a few tips about how to think about social design, which it describes as “a way of thinking about product design that puts social experiences at the core.”
One way to model a social product is by working from the inside out: allow people to create an identity, let them share it and build a community over time. Facebook began this way. However, if community is already curated, as it is via Facebook Platform, you can instead work from the outside in: utilize the existing community users have built, define new conversations and let them continue to build their identities further.
Here is what Facebook considers the Three Elements of Social Design
Facebook profile data can be used to personalize the user experience in your app so that it feels familiar, relevant and trusted by default.
Build tools and experiences that give people the power to connect and share, allowing them to effectively listen and learn from each other.
Users share and interact with others because self expression feels good and rewarding. Help them learn more about themselves and curate their identity.
