I recently launched a website that uses a 3D globe to visualize heavy-industry emissions and information from public registries. The core experience is meant to be open and useful to anyone who visits. I'm wondering whether user signups make sense for this type of site, and if so, what features or approach would justify requiring an account. One possibility is letting people follow a specific route or location and receive updates, but I'm still exploring the idea.

Keep the main visualization open to everyone and add optional accounts later for features such as saved views, watchlists, alerts, annotations, or custom exports. If your immediate goal is simply to notify people about updates, a lightweight email-alert or notification signup would create much less friction than a full account system.
If visitors can already explore the globe and public data without saving anything, there’s probably no reason to require registration yet. Accounts add friction, so it’s better to introduce them only when users have a clear reason to sign in.

That makes sense. I was thinking about optional personalization—for example, letting someone follow a particular route or area and receive updates—but I’m not sure it’s needed at launch.
