Am I suppose to remember that long hash? I'd like if they provided us with some information how this works. Otherwise http://ipfs.io/ seems like a better approach that works in a way that I can actually understand.
In answer to your question: bookmarks have been a long standing solution to remembering names. I absolutely understand that it's not the most ideal solution - but hopefully acceptable for a beta.
Unfortunately, the linked to TechCrunch article doesn't do much to explain how the browser works. One of the original-source blog posts does a (slightly) better job of explaining how things work - or at least points you in the direction: http://blog.bittorrent.com/2015/04/10/project-maelstrom-deve...
The hashes directly represent the infohash for the created torrent website.
I mean, it's a cool idea and all, but why not release a thorough explanation perhaps in the form of a scientific publication?
