No, the Deepweb isn't really all that special. There is stuff far deeper than that too (of course), the real "deep" stuff on the internet usually doesn't come with "http://" in front of it. And yea basically all TOR or I2P does is open those onion or .i2p extensions for you, the anonymity isn't guaranteed. There is also jap/JohnDoe and FreeNet. FreeNet, which was the first one I ever used years back, is kind of a pool of users data shared over the darknet as well as browsing. I really don't know much about the JAP environment outside of it supposedly being the "top dog" of all 4 when it comes to anonymity. I haven't been on the deep in awhile, does anyone know if HiddenWiki is back up? That was pretty much used as a directory and a starting point to find certain darknet sites.
