I just tried to edit an answer to add a missing “not” so as to correct the meaning of what is being said, the system would not let me.
Is this the correct behavour?
(So I have had to use a comment instead)
I tried to correct a broken link in an answer, which was a one character fix. I took the time to search for the blog post the author linked to, edit the SO entry, etc.
Sadly, because I don't have 2k rep, I had to add 5 other characters, wasting my time. The incentive was to leave the broken link alone, thereby lowering the value of the answer.
It would be nice to either
Eliminate the 6 character limit (I get Michael Mrozek's answer about queue flood), or
Split the 2k requirement; maybe 1k for moderated changes (of any length) and 2k for unmoderated edits?
The instruction box at the top says:
We welcome all constructive edits, but please make them substantial. Avoid trivial, tiny one-letter edits unless absolutely necessary.
I think the reason is to try and avoid the queue getting flooded by people posting trivial punctuation changes. Personally I think that probably wouldn't be a big issue, so there might be another reason I'm not aware of
What about to introduce a typo edit category, accessible with less reputation than normal edit? I've just tried to edit a PHP-related answer, where the "s" were missing from the name of a function (so, it's not only a grammar issue).
(For paranoids: inserting/erasing a word, like "not" is also below the 6-char limit, but it can change the meaning of the answer to the opposite.)
The 6 character limit is the opposite of what you should be encouraging.
When someone fixes my spelling or fixes a small but important part of my post, I am happy with that.
When someone adds carriage returns to my post and code blocks to make my post more readable, than I am happy with that.
When someone makes changes to the substance of my post I am NOT happy with THAT.
When you enforce a minimum char limit on your posts, you encourage people to go invent reasons to edit the post. This leads to unimportant, and potentially detrimental edits.
