Some time ago I found a link to a page (or to a blog) where they explained a 'fruit classification' for yuri manga, being 'ichigo' the softer and 'banana' the more extreme. When a yuri/shoujo ai has a fruit in his name, it is the one that corresponds to this classification.

Recently I've been looking for that page, or another one with the classification, but couldn't find none.

Does anyone know where I cand find it or the classification?
