- Main reasons why, are that a lot of the worst disputes and controversies I see, seem to have their roots off site as much as on-site. In other words the action may start on-wiki, but the speculation, concerns, and accurate or inaccurate views and myth-making may take place off-wiki. My job (and probably a number of disputes I get asked to help with) gets easier on-site, if I'm aware of the myths earlier and if people who have concerns can ask those who might know. Obviously people can and should ask on-wiki or by email if there is a worry, but the fact is that many people won't, or don't see fact checking as important.
Also because I'm still finding myself regularly involved on wikipedia, in matters where WR users take an interest, and whatever some at wikipedia may think, a number of editors I'm told post at WR are sane, sensible users. (Obviously some are not balanced reasonable editors, but the point is, there are probably all sorts, and assumption isn't helpful.) So I would like to avoid the hearsay that "all WR users are whatever", in favor of a view that like wikipedia editors, they're individuals, and to meet those individuals. Lastly, because realistically, I do the public face of many of the more high profile Arbcom cases, and I'm one of the Arbitrators more willing to be fairly open to questions on such cases where possible.
What I'm not here for: to spend days justifying things to people who can't think calmly, clearly and productively without games; to argue people out of entire world views such as conspiracy-based thinking; to identify myself personally or discuss irrelevant matters; to get distracted from my core work on English wikipedia Arbcom; to give information and views I woulnd't give on Wikipedia itself, to fight battles and causes. If someone wants serious sensible dialog, then sure. But Arbitrators don't get elected by the community for cluelessness; there will be some here who just want to distract, have fun, play games, or the like - not interested. The users here who want genuine dialog, and act that way... those will find I'm open as much as my Wikipedia work and the best interests of the project allow me to be, and as they approach me, that's how they will find me.
That said most of my wiki-work is at Wikipedia itself. I don't do politics so even other wiki sites such as meta aren't places I go unless relevant to enwiki work, much less off-site like this. I just think there's a chance that this might be something I should do, or at least check out, rather than rely on hearsay.
