Google’s new interface is nice, and it seems like it even works a bit faster. However, I’ve seen a few blogs mentioning they replaced tags with folders – the blog I linked to isn’t one of them – and it appears they just renamed the tags as folders and put a little folder icon next to them.
As I said, the new interface works great, but is there really a large part of the Internet populace that can’t be comfortable with tags unless they have a folder icon next to them? :)
