Again, I think there are articles that should be locked. These are articles which there is nothing a player can add to, like Chronicles.
Item descriptions are an area players might be able to add useful content and have in the past.
Consider Moon-Material Reaction or Planetary Commodity chains as an example of item descriptions where player editing makes them more useful and relieves CCP of having to do the leg work to connect the dots. It
was* immensely helpfully to be able to click through the reaction chains from the T2 component down to the basic moon material and understand what was in between. CCP does not have this setup yet in the database. Luckily Items are not locked, so users can add information along the bottom.
*It appears the update has broken some links or should spend a little time when I use it adding basic content to the items page.
At the end of the day it is CCP's decision what they want to make Evelopedia. I respect that, but it does not mean I cannot complain about the decision.
If it is meant to be a sourcebook, then some of us (myself included) need to reduce our expectations of what Evelopedia can be. We might be lucky enough to have a record of some of the history players help create, like the
Great Northern War or a
history of Band of Brothers. But it would mean that pages for
Lai Dai Infinity Systems or
NARAKA. would not exist. They are not important enough to rate a page in the greater story of Eve.
On the other hand, if it is meant to be a wiki, then I think a much smaller portion of Evelopedia should be locked. In my opinion, only when CCP is truly providing content through Evelopedia would the page be locked. Chronicles are an example, but even they are not just posted to Evelopedia, and arguably links of references at the bottom and links to eve-unique terms might add to the Chronicle.
As for player abuse, it becomes the duty of the community to fix those errors as much as CCP. Its a wiki, the reader is warned. The benefit of a wiki is if you see a problem (like someone calling the Gallente ultrasocialist),
you can fix it!Immediately seeing a page is locked/with CCP edits makes it a scared page that is forever immutable, even if it is wrong and in exact opposition to something CCP's other material. A knowledgeable user might select an area they are knowledgeable about and watch the pages for changes, checking the changes to Drone Regions or Black Eagles for what changes are made, by whom and with what references. You can be a steward, a volunteer without CCP's "official" blessing other than that it is a wiki for every user to edit. Players are the staff to watch pages and point areas of conflict to the staff.
