I'm not claiming to have full technical knowledge of Ripple (but neither do I have that level of knowledge of Bitcoin), but I do know enough about it to believe that the arguments in defense of it all seemed to ignore one basic problem many bitcoin followers have: it's centralized, and there is no indication that this will ever change.

Rampion's post is an excellent summary of why I don't trust, and don't feel like supporting Ripple (I agree with everything except the last paragraph about the founders "cashing out". They will never do such a thing, as it would instaneously destroy their wealth in the process).

If you feel that anyone who's critical of Ripple is just (consciously or not) trying to defend his own get-rich stake in Bitcoin, then I guess I can't really argue any further.
