The only reason I can think of against it offhand, would be that code/snippet nodes tend to be long in actual content, and we'd have to just display the text parts. Currently the frontpaging code only deals with displaying entire doctexts of document type nodes, and not special fields, which snippet has. Not that they wouldn't be impossible to add though.
Other than that, I tend to watch neither the Gates nor the Snippet section, so I don't mind either way.
I may be interested in a "Best Snippets" though, arranged by Rep and/or "Type" somehow..
