Any advice for a newbie trying Ripple?

Thanks, in advance.
My opinion that Ripple will not live by three reason:
1. No benefits for nodes to support the network. A few people will do it for free.
2. OpenCoin holds almost all of XRP, it is impossible to put it in a circulation in fair way for to satisfy all of participant.
3. Too complicated for understand.
The trust and liquidity providing features are also flawed.
