Depending on what your curriculum is, blogs can be very beneficial
and rewarding. Blogs can also be a source of instant feedback, as well as a
loud voice when needing to communicate to the masses. Blogs are an inexpensive
way of advertising your message or product. When used for the wrong reasons,
blogs can quickly destroy someone's reputation without knowing who sent the
damaging information, (accounts can be made anonymously). Whether the
information that’s being blogged is good or bad, it reaches many in a short
time.

I believe if the blog isn't written
well the proper message can be lost due to improper communication. (The tone of
the message the blogger is intending to send is lost, and not being fully
captured as the blogger intended).

I also believe the lack of correct
communication will not allow the respondent to acknowledge the true intent of
the message the blogger is intending without being confused, and continually
asking more questions.
