Here are some of the expectations I have when someone leaves a comment on my blog:
What type of comment is acceptable:
1. A nice comment that gives me compliments about my post.
2. A comment that can relate to what my post is about.
3. A comment that asks a questions about my post.
4. A comment that gives me constructive criticism.
What type of comment will I put in the trash:
1. If its a rude comment, then I’ll put it in the trash
2. If its a comment that is mocking what I’m writing about.
3. If its a comment that has no constructive criticism, but straight up criticizing without telling me how I can improve the post.
