Touring and generally looking at buildings is, in my opinion, an important part of being a developer. Whenever I tour a project, I always learn something new. Because invariably, someone will say something like, "the building inspector made us do X." Immediately after you then email all of your project teams and ask them if they've run into this same problem. And then, hopefully, you're a little bit better than the last project.

This kind of knowledge transfer is a good thing, but I also think it's a reminder of just how opaque and fragmented information is within our industry. There's a lot of information and experience that simply isn't stored anywhere, other than in someone's head or deep on someone's hard drive never to be found ever again.

Sometimes it might be part of a firm's competitive advantage and they don't want to share it with others. That's fair. But in my experience, most people in this industry are more than happy to share what they know and where they've made mistakes. It helps us all get better. But might there be a more effective place to share this knowledge beyond individual conversations, conferences, building tours, and group chats?

There has to be. And my prediction is that it will eventually live on a blockchain.

This week Strong Towns has been running a great social media campaign called #BuildHereNow. 

The way it works is very simple. They asked people to get outside and take photos of vacant and/or underutilized properties in their town or city and post them to Twitter or Instagram using the hashtag #BuildHereNow. The goal was to start to identify properties that could “use a little love" and to encourage city builders who might need a little push to develop a particular property.

I’m a big fan of crowdsourcing information and I love the idea of digitally annotating buildings and spaces. In this case, it’s about pulling together the desires of the community,

Hashtags are a great way to quickly make something like this happen, but I would love to see a purpose-built tech platform do this in a more permanent way. Of course, it doesn’t just have to be about developing. Buildings are rich in information; hopefully so rich that a platform like this could survive.

If you think about it, property titles are already a form of annotating real property. So this isn’t really a new idea.
