One of the ways I think Neven stands out is his ability to report dispassionately upon the issue, without an ulterior motive or vested interests (and even scientists will tend to have at least some of these, even if only in terms of not being able to discuss things until they publish, an unwillingness to appear alarmist or to subject oneself to professional ridicule etc) getting in his way.
Without the bias of agenda and the restriction of procedure, a unique resource has been created - a striking work of high quality citizen journalism. I doubt many scientists would be envious, in the sense that they presumably chose science to do science - not to talk about it - but it is a striking achievement.
I always look at any information and ask myself what the bias is - what the agenda behind the words is - and in Neven's case I am unable to detect any significant such bias or agenda (beyond perhaps some level of concern about the implications of the events in question, which is only human).
The importance of the work Neven does, and the significance of the achievement in gaining recognition from other parties cannot be overstated (the last part important - it's easy to talk without anyone hearing you online).
Now we just need to capture and clone him, and get at least another ten such people equipped and capable of doing the same for the other big changes underway in the earth system.
