I have noticed lately that there have been a number of old, low vote number (<1) posts re-appearing at the top of the forum. This is also happening to some recent highly voted posts. It would seem that the reason for the rise in the post visibility is that minor edits have been made to posts, usually to the question, not the answers.
Now I can see that editing to improve spelling and/or grammar and readability is a good thing and not to be discouraged, especially for posts that are likely to be seen by the wider community and potentially attract new users. However, it feels like some of these edits are made, not in the interest of making the posts better, but more for reputation farming.
So, the question is: should we be approving such edits, when they do not substantially improve the style of the post nor do they change the content of the post in any discernible way?
Edited to add: here's one Cheeses with artificial ingredients?, I approved the edit a couple of hours ago, not realizing that it was a post from 2010. Another here: What does simmer mean?, and here: Pizza stone soap? I realize that the last is a recent question, but the edits were very minor spelling fixes.
