Are there rules for commenting on blogs? You bet!
The rules for commenting are the same for in class. There's actually only one rule -----> Respect.
Think of what you'd want someone to say to YOU.
Compliment... Example Starters: "I like the..." "I like how..."
Comment... Example Starters: "I agree..." "I disagree..." "I think..."
Connect... Example Starters: "I have also..." "I have seen this..."
To keep the conversation going, ask a QUESTION!
Question... Example Starters: "I wonder...
why / who / what / when / where / how..."
Perhaps even leave the URL of your blog as well, so you can continue to talk about the topic.
Two more tips before you post...
1. Use correct grammar and punctuation - it makes you more credible (believable).
2. Ask a question to keep the conversation going, then check back later to see if he or she answered you.
Essentials of a Great Post
1. Catchy title
2. Includes at least one visual (your own photo, cartoon, video, Glogster, Wordle, Thinglink...)
3. Interesting topic with the passion of the author coming through - your message is clear
4. Well-written, and not copy / pasted from somewhere else
5. Proofread & spell-checked - your best work
6. Written in paragraphs or prose format
7. Includes links to other websites on similar topics
8. Includes a question to the reader - challenging him or her to think

What does a blog comment look like?
It provides feedback, answers a question, adds on to the information, asks the blogger a question, gives a compliment... It is a short conversation between the reader and the writer.
