My personal policy to editing wiki articles:
If I feel an article needs to be edited, I will check the Talk page to see if anybody has the same sentiments. If so, I will proceed to make the edit. If not, I will put a recommendation in the Talk page for an edit.
Basically, I will not make any edits to a text unless at least 1 other person is in agreement. The exceptions are: (1) when something is obviously and incontrovertibly wrong, and (2) spelling and grammatical errors.
