The Roam Research Networked Thinker

A researcher, academic, writer, or knowledge-intensive professional who uses Roam because it is the only tool that treats the connection between ideas as a first-class object. They write in Daily Notes. They [[bracket]] everything. They have a graph with 3,000–15,000 nodes that they've been building for 2–4 years. They know their graph is their most valuable intellectual asset. They also know that Roam's development has slowed, that the tool has rough edges, and that they've considered migrating to Obsidian or Logseq at least twice. They haven't migrated. The switching cost is partly the data — mostly the habit.
