I would have to equally throw my hat in the ring with others in that I would absolutely loathe it, hate it if someone else had edit rights over my pages/content. As Bob and three others have already stated, one of the things that makes SP stand out from a wiki-site and other sites is the 'flavour' or spice each page has in accordance with its' owner writing ability. Some pages (overview) almost read like poetry snippets. When someone can combine creative licensure with factual/statistical employ, that's talent and skill and though not to reward someone like that who writes as such, but to give a stranger edit rights, cheapens that pages' character.
So bad idea to full & open edit rights. No Wiki
As to term limits in updating beta, this is gonna be a hard one to nail down. Fletch's 90 days is agreeably too short but posing a limit of 1 year (365 days) can equally go too short or too long. Some pages out there as another user already mentioned, simply don't need updates annualy. Some pages, like say, Long's Peak, Grand Teton, Mt. Elbrus, Mt. Blanc etc. would definitely stand to profit from frequent changes and updates. I don't know how the elfs would track something like that. Would us users see the time of last update and do something about it ourselves if we wished? Is there coding that would send off a flag to the elfs after a certain amount of time has elapsed? If so, that's a lot to ask of Bob, Gangolf, Matt and the remainder to take care of considering the massive amount of beta on SP these days. I think the X
-number of eyes from us users would be substantially better to track these things than the n
-number of eyes of the elves.
* I do like having the "additions/corrections" feature having a greater visibility.
* I do like having an additional section just above the images on pages for 'other user' added content.
* I do like expanding the PM system so that users can retain more control about contacting other users in regards to
neglected or orphaned pages...lastly falling to the elves when after repeated attempts at contact, no relpy is made.
* I do like having a section on the front page highlighting random users based on A, B, C criteria kinda like what weThat's my .02¢
have now for images and pages and articles. We have an awesome community here on SP but often, I feel there are a tonne of users that
'fall through the cracks', as it were.
