Sounds like something's gone wrong if you're not being productive when using the space. How often do you go there? It might have to do with the frequency of seeing others. There's going to be a certain amount of showing off when you see someone you haven't seen in a while and hasn't seen this cool new thing you've been working on. But that wears off after meeting up for a few days in a row.

Today I coded a new feature for my latest startup, gave a tour of the space to some people, learned about Chef and how I can use it for my fleet of servers, fixed some major bugs for clients, did some estimates for potential customers, installed a few Drupal modules. And I've only been here since noon.

It's all in how you use the space.
