I am surprised, how new SCN is allowing me to change somebody else's WIKI (I just put "." only in the heading), but still it allowed me.
Is it a common in WIKI, anybody can change anybody's wikis.
I am confused :-(
Fortunately or unfortunately, it has given me 2 + 2 points also (4 points)
I believe I have only changed one but it has given me points for another change.
It seems this a good way of getting points for the people who are craved for points.
That means SCN will allow to change (though minor change) still get points. I wonder why SCN is allowing the change of somebody else's WIKI.
If somebody deletes the whole text then, what is the integrity you have provided here.
Great discoveries with wonderful new SCN
It was the same on old SCN and it is the same on new one.
Sharing the access to wikis with others - is the main idea. Each wiki doesn't belong to anyone concretely. I'd suggest to run through general wiki definition http://en.wikipedia.org/wiki/Wiki.
Regarding deleting the whole content - there is the version management in place if you haven't noticed. And moderators which can take actions to prevent an inappropriate behavior and content there.
About points. Here I'm agree with you that something should be done with it. May be analyzing changes which were made to the content. Or setting monthly limit on gaining points for changing (not creating) wiki content.
I should emphasize on your point # 3 regarding points. In my opinion, the original should allow the points, if the next person has modified. Otherwise, just by putting commas etc., still people are in a position to gain points. Definitely, this is not a good point.
BTW, have you seen this blog One Big Happy Family: The New SCN and the Wiki?
