I was talking more about my datafeeds for AllPosters and Amazon -- I'd prefer that they only index specific product
categories, and indeed, those are the only links I put in my sitemap -- but G* follows
every link (of course), so I end up with it indexing 1000s of products unrelated to my site. Which is fine, but I'm on shared hosting (with "only" 4500MB space and 100GB bandwidth)
