Skyshelf is a manually curated directory. Every entry has been watched, evaluated, and added individually. There is no recommendation engine, no engagement metric, and no sponsored placement.

The focus is on channels that value depth over frequency, with a bias towards smaller creators.

• 01Accuracy. Content is factually sound and updated or annotated when errors are found.
• 02Depth. Explanations go beyond surface level. The viewer comes away with a genuine model of something.
• 03Clarity. Complex ideas are communicated precisely, not simplified into uselessness.
• 04Independence. No significant sponsorship pressure distorting the content.
• 05Longevity. Preference for content that will be relevant in five years, not just five weeks.

The directory is reviewed weekly. New entries are added when found. Existing entries are removed if the content is taken down or no longer meets the criteria.

It-s-a-me, Rakhim. I also building minifeed.net — a place for well-curated RSS feeds, and exotext.com — a simple blogging platform.
