The evolution of MetaFilter: this week Paul Ford and Rich Ziade talk to Matt Haughey, the founder of MetaFilter, the collection of sites and communities that Paul describes as “one of the real success stories of the web.” The conversation covers Matt’s early career at Pyra Labs, the accessibility of digital technologies, his current job as a writer for Slack, and how if you spend enough time publishing online, you’ll inevitably attract the attention of two groups — trolls and lawyers.
