I think the issue isn't the vouching, it's the speed. If I'm at a conference and am talking up Citizendium to someone and they say "that sounds interesting", it'd be great if I could vouch for them to a constable who could then approve their account very quickly. I still think that what's keeping us from collaborating is lack of a real-time backchannel - IRC or something equivalent. If I could hop on to IRC and find a Constable there to do it in real-time, we could collaborate on things faster, and approve users quicker.
Alternatively, just have a system where those who have made over 1,000 edits to the wiki (say) could basically opt-in to serve the registration role that Constables serve - in the UK, we have the Police Community Safety Officer role, or the "budget bobby".
Well said. Being able to send reviews and comments (i.e., not exclusive to Approval) is an interim step.
Consider an Approval-related scenario, however. I have an article, Torture, that may well be close to Approval, and, I believe, is an important and topical subject. No current Editor has wanted to take on the approval process.
When I was actively writing it, I happened to correspond with an academic specialist in the field, who was quite pleased to have looked at the article and found some material that was new to him. We discussed by email, since we obviously could not on the talk page.
Now, what if he wanted to move to a higher level of participation? He happens to work for a degree-granting U.S. government research institution, so his articles are public domain. Even if he wanted to take an existing paper and adapt it into a CZ article, he'd have to get registered, and, while his papers are public domain, I can easily see him wanting to use a personal email so as not to get into bureaucratic politics.
Of course, I'd like to get him involved in Approval, which would require Editor status. I'd like to be able to say to him that even if it took a few days for Editor approval, he could send his immediate thoughts to the Approval Manager, and there would be some commitment to use them.
The latter, however, remains an unsolved problem. If we get a detailed review from a specialist, will a Workgroup Editor in the general area, who is not a specialist who can nominate for Approval based on personal expertise, progress the process?
