The singular dna of the web is connections.

Call it community if you wish. Consider it a flash occurrence or an ongoing event. Define it as a gesture or a comment, a wall utterance or a full-blown blog community.

The one thing that the web does so powerfully is to engage others while we experience life ourselves. And to create a dynamic collective memory of a shared experience.

As powerful as this is, it is also quite new.

The comment string of my post on 9/11 was full of outbursts of ‘where I was’ and ‘do you remember’. It was clear that as recently as a decade ago, before the social web existed, we experienced this attack without broad community support, and it left many of us isolated in our thoughts and memories.

If this happened in the last five years, our memories would have been shared, our feelings commemorated in countless posts and photos. The sense of understanding greater, more widespread because of the community around it with the web as our platform.

Every day now, with Facebook, Twitter and blog communities, experience around most every public event, from the horrors of mass shootings to the media shares around Breaking Bad have their platform and a shared memorial to the event.

This is the status quo for all of us today.  We live in the dailies of our own life movies. This is nothing but positive, nothing if not a giant evolutionary step forward.

I’ve always believed the web’s greatest value was in the connections that it enables and the new memories it creates. I first started thinking about this around my mom’s birthday a few years ago. I wrote a post back then about how her generation had missed the great upside of connecting and making new friendships as age, mobility and ennui closed the door on the future for them

Memory is the encapsulation of conjoined events in time.

Individually they affirm our past actions to ourselves but they also isolate and freeze time rather than making it a step to something more.

Collectively, memories meld people together, build a base of shared reality to create ties for the future.

Community is, in many ways, that entity that keeps layering on intersections of instances in time, engendering trust and understanding and building steam for future connections as the group broadens and deepens.

I believe this will be a large part of the web’s legacy.

Collective memory as an idea is also a powerful filter for those of us building products or communications platforms, communities or networks.

What we realize about the social web especially, is that once we stop flagellating around like adolescents and start thinking about shared events or ideas as connectors, questions like why our customers or friends should care or share come into focus. We stop counting KPIs and start thinking about the why of connecting with people.

Once we internalize that community happens on the street witnessing an event, online around a discussion, or in a connection around a homeless pet for adoption, we are understanding that inclusiveness, even around the most divisive topics builds bonds, community and social memory.

We talk community. We lionize context as the pinnacle of design. We equate platforms to places and the ease of creating friendship to the new norm that the web somehow makes possible.

All are true.

Facebook works because it gives collective voice to being part of an event or an emotion, a decision or a memory. If it is about anything, it is about collective affirmation.

When I look at closed groups on the web, they are striving towards the same, dragging connections and re-forming them to collectively discuss or commemorate.

In many ways, network effects is just that, at an atomic level. Connecting, experiencing and memorializing. Repeat infinitely and you have not only a key cultural and behavioral truth behind network effect but of virality itself.

Tech pundits say that Twitter, Facebook and Linked In have sucked the social oxygen for innovation out of the web.  I’m thinking just the opposite. These platforms are the railroads before the roads, the express trains before there was a need for the local stop.

Our social memory on the web is just hardly a generation old. The things that billions of people do daily barely had names five years ago. We are at the most nascent stage of social evolution.

Today, for the most part, local and neighborhood are web empty. Extended intersecting communities that leapfrog off the big nets are just being defined. And marketplaces building on the transactionless nature of the big social nets are just starting to pop up everywhere.

Technology has been the core driver of change and innovation for the last two decades. No longer.

My sense is that evolving behaviors, shifting cultures, new ways of consuming, decentralized communities and flash events are the catalyst and the direction for what’s coming next.
