Your arguments don't hold. The point about blockchains in general is: it's an interesting new technology. Do you disagree?
Since we can agree on that, what is wrong about people trying to put that technology into practice? No one has ever claimed some specific blockchain application would be profitable, but people are trying to put that thing into use. What is the problem with that?
Some time ago I had to look for details on a transaction I did on Ripple and couldn't find a simple website that took a transaction id and showed me details on that transaction. Why is that?
I see you're linking to Bithomp here, and that's what I found, the only one, but still it wasn't sufficient. Bithomp is confusing and doesn't show all information, just a quick (and confusing) summary.
So this is basically a blockchain, but with transactions instead of blocks, and diverging-then-converging graph instead of a linear sequence of blocks (like a real family graph instead of just one-parent-one-child families common in blockchains). Looks nice, what are the problems with the approach? (the paper only lists the benefits).
I thought this would be more than just a list, that it would contain some information, a brief overview, a table of features of those currencies, but no, it's just a list.
