...because the URL points to Snap! with the actual project appearing as data to the link. It'd be nice if the forum recognized URLs of projects and put the project's name instead of Snap! 's name, and the project notes instead of the Snap! propaganda paragraph. Besides being more helpful to the forum reader, that'd encourage people to write project notes in their projects!
I would be a little suspicious of a link to Snap! in the Snap! Forum... but anyway, as I said, it's easy to fake a link, caveat emptor and all that. To the extent possible, I'd like our lives to revolve around good possibilities, not bad ones.
