The only other thing I can think of is &quot;name recognition&quot;.<p>E.g. I love Hans Rosling (or James Burke, Carl Sagan, Niall Ferguson or whoever) so if I see that something is based&#x2F;stars&#x2F;includes their work I&#x27;d likely be interested.<p>This is obviously not applicable to many things though, and can be somewhat included in a description anyway.<p>And thanks to you for taking time to read my comments :)
