Should I encourage their engagement...knowing what I know?

Not everyone I know thinks this is such a good idea. The best answer wins a gift card as incentive to help me find out.
Let me begin by explaining the purpose of this post.  Engagement :) I know my kids love the freedom of expression on Facebook to create a unique voice. I want to effectively transfer my students mastery of engagement with their audience on Facebook into the classroom. I want students to use the same creative methods and tools used to create well written media they post on Facebook as a rubric for blogging or producing evidence of mastery of core subjects they are expected to explore with rigor all year long. What do you think? Should I post these "tips" as the new rubric for writing assignments!!?

     Use at least 3 of these tips to make your project engaging!!!

• Use a self explanatory  photo for fun
• Keep your idea concise - shorter post
• Use emoticons to get a response
• Preface your work with should, would, which and who to get a response  (why is a loser)
• Have your audience "like it" for a contest (think peer editing - final presentation)
