Well, we may all dream. For photos, most of your questions are answered by the categories in the picture section. Usually, the categories are being adhered to very well with exceptions marked as such - thank you so much to all contributors for doing that!
But I fully agree with you where videos are concerned - on an "old" 3000k DSL line, it takes ages to browse through all of them and it does take ages to watch them all regardless of the connection. So yeah, could we please all agree to properly tag all videos? That would be great indeed!
