- Ripple is a system for exchanging IOUs that obfuscates counter-party risk,
- ripples are an essentially valueless token with a misleading name.
The first part is slightly wrong (the "obfuscates" part), Ripple even makes it much easier to assess counterparty risk, you have to enter your counterparty that holds your assets for any trade (except for XRP, where the network itself is the counterparty, like BTC on Bitcoin). "Rippling" (the automatic 1:1 trading of 2 currencies in the same denomination e.g. BTC/Bitstamp and BTC/TradeFortress) is disabled by default in the client now for quite some time.
I would have phrased the second part differently because the same "essentially valueless" applies to BTC too, since they are not backed by anything and thus only have utility, not value. "Misleading name" is a bit weird, because I'm not sure where a name should "lead" to instead, I agree though that something like "Droplets" or something else would have made it easier to understand that XRP != Ripple. Other systems like Mastercoin for example though don't even seem to care about clearing this confusion...
It seems to me this Tl;dr is slightly cynical/negative and I would recommend to think about how a similar Tl;dr would apply to Bitcoin... and this is coming from someone who (based on your time of signing up here) very likely holds more BTC than you do.
Like I said one post above, how can I evaluate the counter-party risk? Also, I'm still not convinced that the IOU credit risk is just a function of the gateway's credit worthiness. Don't gateways swap IOUs? Isn't that the whole point? So wouldn't I need to also trust MtGox's or RBS's assessment of their counter-party's credit worthiness? And what about the counter-parties of the counter-parties, ad infinitum. This is what I mean when I say "Ripple is a system for exchanging IOUs that obfuscates counter-party risk."
No, gateways do not swap anything. This is the job for market makers (seriously, read the whitepaper that tokeweed linked!) and while gateways can make their own markets, it is by far not a requirement for them to do so and it is also (as anything in Ripple) easy to see they do and to what extent.
