Neil Mitchell:
I don't think restricting editing to registered users is a significant turn off if registration is simple.
It really really is a turn off. Sometimes when I spot a mistake, and I'm at a computer where I haven't logged in to hawiki, I don't bother fixing it. No one wants to have yet another account, to fill in their personal details yet again.
I appreciate spam is a problem, but turning off unregistered users is a trade off - less content, less spam, less open to people joining - its not a free solution.
It is a trade off, but I am not (yet) convinced that it is a very serious one. The question is whether we want to make (almost) all of haskell.org editable, so that, for example, people can put links to their own libraries, tools, and papers up, or that they can share other Haskell knowledge. Not all, but many of these things are not casual 1 minute updates anyway. For these, moving from nobody, except two maintainers, can edit to anybody who can bother with 1 minute registration fuzz can edit seems already like a rather dramatic change. Besides, I definitely have a very lightweight registration in mind. No personal details, except an email address required. Manuel
