I'm a fairly experienced Stack Exchange user, and I just noticed that someone made a very poor edit to my question, cutting out details and changing the meaning entirely, in order to shorten a question that was already only 3 sentences. It seems to me like you guys should perhaps either raise the rep threshold where people need more rep to edit without peer review, or better educate your users here how and why edits should be made.
Maybe this was a 1 time thing, but I find on these sites single users, depending on the amount of time they spend on the site, can make alot of these incorrect actions perhaps even without being noticed, so I decided to mention it.
I dont do much editing on the SE network, so I dont know, maybe edit without review is standard at 2K, but I do know the way and reason edits on Stack Exchange should be made after following meta across the various sites.
Edit: After I commented pointing out to the editor that it was a bad edit, he did respond favorably, so perhaps it isnt so much of a problem in this case.
