Just for the informed discussion, some thoughts on what a bot could do when we would decide to have some sort of discussion/comments on the wiki.
It should be possible to let it manage some sort of "recent comments" page.
* Transfer new entries from a possible Comments-section of a page to a central Comments-page, where people can reply and find comments without browsing "Recent Changes" or all pages
* Maybe also back from there to the individual pages
* Delete/archive old stuff from the comments page (not that standard, but I have an idea how that might work)
Other and probably less of a hacky probability would maybe (that's not my territory anymore, TwiNight?) to have a Comments-template that automatically also shows up on a central page? So that to add a Comment on a page, you add some {{Comment|Text xyz}} and that automatically also shows up on a page [[Comments]].
Still not sure if comments on the wiki is still the way to go, but I can imagine that is an additon to the pages not just have the "official" article, but also some not so polished ideas. Would also maybe lower the entry-boundary, that you don't have to edit in someone elses work and change that, therefore thinking that your contribution must be really really worthy, but just can add some ideas in an "inofficial" section below.
