Still snapping some. It's actually much harder to remember to make social media now that I'm out of YC.
When I was at YC, there was a defined schedule, so I had lots of free time to mess around on snapchat. Now that I'm back in the startup world, I spend most of my time thinking about and working on my company, and forget to snapchat.
YC is structured by-design to have time you spend as a partner working with companies, and time to do whatever you want. I liken it to being a university professor.
