In this post I asked whether I should continue barraging my peers with edits. I still have one question, though. I've made around 20% of my reputation off of edits. Is this honest, or should I cut back a bit? Reputation is supposed to be a measure of how much the community trusts me, but it seems that my reputation in this case is partially based off of grammatical skill rather than knowledge of Ubuntu.
Yes, it is totally fine.
Besides, reputation from edits are capped at 1000. So after your 500th edit suggestions, you will stop getting reputation.
Also you do not get reputation from edits, but from "approved edit suggestions". Knowing this, when you reach 2k rep, you will no longer be able to suggest edits on posts, instead you will be able to edit them without waiting for someone to review them. This will stop you from receiving the 2 rep per edit suggestion.
However you would still be able to receive 2 rep from edit suggestion on tag wikis until 20k.
Just to add another way of saying it:
The longer you are on this site, the more you realize that good questions are the key to a better quality of the site. Good questions are clear about what to answer and invoke good and clear answers.
If you play a role in improving the quality of questions (and answers), you are doing a job of major importance, and deserve the reputation you earned with it.
