We should be able to vote on our own community wiki posts
As far as I know, a post can become Community Wiki in these cases:
- For Questions, you need to flag it to a moderator OR when it gets edited by a number of users.
- For Answers, you can set it yourself OR, again, when it gets edited by a number of users.
I think that at least in the second case we should be allowed to vote for the post, even if we are the original author. The reason is that after being edited so much, that post is not really ours anymore, if you get what I mean.
I also think it'd be useful in some Meta discussions. Think about when setting policy: You provide the canonical "I agree" and "I disagree" CW answers for the community — they haven't been edited, you set them — but you still can't vote for them and actually show your approval/disapproval.
I don't think there's going to be abuse since you can vote once, and you'd be promoting a common post and not yours, and it won't give you reputation anyways. But instead, you'd be voting on the resulting post which probably has only little of your original wording.
I honestly fail to see any compelling reasons for not allowing it, but who knows. I've searched for any related posts, but it seems nobody asked before.
