A few weeks ago, we heard that the San Francisco Port Authority had red-tagged Pier 38 — putting up warnings that the space was unsafe. This is a big deal because Pier 38 is something of a tech hub. It's home to tenants including Dogpatch Labs, Polaris Ventures, Automattic, True Ventures, 99 Designs, EGG HAUS, and more. While Robert Scoble grabbed some pictures showing just how serious these notices were — it's never good to see a big red sign with the word "UNSAFE" on the door to your business — Polaris' Ryan Spoon downplayed the warnings.
