You cant escape a digital marketing site or meeting without hearing the term social media. Thus, I wonder if there is a social media ettiquette guidelines to go about it. I saw this site by popular blogger Tamar W - http://www.techipedia.com/2008/social-media-etiquette-handbook/
I do agree with some of the points. Are there others you think its missing that needs to also be part of the ettiquette guidebook?
