Tips on writing good comments

Here are some good tips on writing a good comment:

• Start with a greeting.
  
• Be nice.  Compliment the writer in a specific way. Tell them what you liked about their post.
• Make a connection - does their post remind you of something similar?
• If you learned something new, tell them what you learned. 
• Ask a question
• Add new information.
• Make sure your comment is relevant and related to the post. 
• Check to make sure no one else has already written the same comment.
  
• Don't reveal any personal information.
• Use proper English - check for capitalization, punctuation, spelling and grammar. 
• Don't use too many exclamation points.
