A stream is like a river – it flows continuously, carrying information forward while preserving everything that came before. Think of a blog, a journal, or a public thought stream 2025-01-17_18-31. Each new entry adds to the historical record without disturbing what came before.

The value of a stream lies in this accumulation: you can trace the evolution of ideas, see how your thinking developed, and extract insights from the patterns that emerge over time. A stream isn’t there to remind you of tasks you need to complete – it’s more of a running log or narrative that simply keeps growing over time.

Many streams are treated as append-only, where entries get added but aren’t edited much, allowing you to see the evolution of an idea (for instance, older blog posts or daily journaling), see 2.16.
