I notice that Wizzley's categories more-or-less mirror Squidoo's categories. I think Squidoo's categories, however, are one of the big weaknesses of the site--in many cases they seem to be a little haphazardly created, and they don't correspond to the ways that seem most natural to me to organize subjects.
I have some suggestions for the Coffee & Tea category, because it's one I publish in a lot. I'd really like to see a sub-category: "Tea Companies, Brands, and Shops", separate from "Kinds of Tea". The reason is that one focuses on a business, whereas the other focuses on a type of tea which may be sold by many different businesses.
For now, while the category on Wizzley is small, I think it would make sense to consolidate "Tea Pots" and "Tea Accessories" into one category, "Tea Pots and Tea Accessories".
Maybe I could get thinking about suggestions for other categories too. I think categories are a weak point of Squidoo so I think it would be good to brainstorm re-organizing them, especially for categories that don't have many Wizzley pages published in them yet!
