blogsites the same as posterous are good because you can uplaod your work and recieve comments on your work and ways to improve if a buissness all had accounts on a blogsite like posterous the people in the buissness could share ideas on work and communicate from home and get ideas for things and you could see what they are up to and see if they are making any progress with things. 

you can also see other people's work from outside of your buissness and say look at what they are doing this could be good if we do something simular so you can suggest ideas from outside of the buissness providing it doesnt go against any copy right laws. 

you are also able to edit your work without starting all over again as well as save your work so you can come back to it later and finish it off. 

blogsites are free which will save you money! 

Also blog sites are free therefore you do not have to have any complications on having to pay for them. They are already designed and you dont have to make a whole new site.  

They are so easy to publish. Its lie a broadcast you can just broadcast in a click therefore you can communicate so quick and share with people what you make and what you are gettingt up to alot faster than a phone call.

 Also most websites have apps on phones such as facebook on the iphone app and you can communicate easier than getting your laptop out and starting it up you can just go on the facebook app. Same with twitter!
