The complaint is more websites don’t have a distinct smell.

Walk through a library and a dozen different books can all have distinct smells. Perhaps this book was taken to the beach a few times while that that one used a slightly unusual glue. Based on book age and the publisher involved you can even encounter similar smells looking at different copies of the same book at different libraries.

So yes a computer has a distinct smell the way a library does but that smell doesn’t change based on the knowledge you’re browsing.
