The .org profile
The extension carries institutional and noncommercial associations. Strong dictionary terms and category-defining names can have real value, but the buyer universe is different from direct-response commercial domains.
Use extension-specific evidence
Evaluate mission fit, authority, memorability and likely organizational buyers rather than applying a simple .com discount mechanically.
Run the domain through the same framework
Extension quality is one factor among naming power, clarity, commercial intent, scarcity, build potential, liquidity and buyer depth.
