Blogging in Communications

Blogging is very important to the communication field.  It is a chance to promote yourself and a product or service you are interested in.  I personally have never blogged before, but I think learning about blogging could help me in my future career.  I want to work in PR and being educated in blogging could be helpful because that is a job requirement in alot of establishments.  I want to be prepared to go into the field of communications with all the tools of the trade.
