I have this idea where instead of generating hashes, you send links and/or text to other nodes, similar to Reddit submissions. If you get good ones, you can "upvote" them and forward them to more nodes, maybe with a comment. The most upvoted link/text in 10 minutes becomes the next block, and coins are awarded to the original submitter who signed it with a private key and attached a public key. The coins can be traded similarly to Bitcoin. You can also go down the block chain to see all the best links ever.
This could also have an updated client that displays the text and links inline. So you can hit "next" to see the next one sent to you, and so forth, and different quality filters or sorters.
Thoughts? I only came up with the idea 30 minutes ago so don't hate on me too much.
