I've got a few sites that the index page doesnt show up well in search results beacuase theyre not my main landing pages, just legal disclaimers. Once they mature, some are less than a month old, and I add hardlinks to the index.html page the SE's should index it better.
I cant see an index page getting spidered much if its not your main landing page. Usually its the index that links to the rest of your site, not your sub directories linking to your index. No path to your index no spider of your index I would think.
Matt - I'm with you on the punctuation, I'm all about that theory, despite what the experts like Danger Dave repeatedly tell us
