When you close the welcome card, a short tour walks the sidebar once: the dashboard, the radar, the editorial board, Publish and its stages, templates, recipes, the network pages and your account. The radar opens in the by-network view for a new workspace (one panel per network reads better the first time); anyone who already picked a view keeps it. And a brand-new account no longer sees "new since your last visit": the welcome card is what it sees, and the updates card starts counting from that day.
