It's perhaps a bit out of the scope of your thread. However: When 
congestion control is one of the fundamental mechanisms in the internet, 
we should employ mechanisms which are a bit more robust than riding a 
unicycle. And from what I've read here in the list and quite some 
private discussions, particularly on the buffer bloat issue, I'm not 
fully convinced that we really learned how to do it. At the moment, 
referring to a picture, we are mounting the unicycle, falling down, 
looking around where the unicycle is, mounting the unicycle again, 
falling down.

In private discussions, I'm pointed to clean slate approaches, e.g. 
RINA, and actually, from what I see and what I'm told, in all of these 
discussions I see a mixture of science with personal interests, 
politics, bitterness and an astonishing lack of mutual respect.

Sometimes I get the impression: The louder people speak, the less they 
have to say.
