I am happy to have this opportunity to share with all of you the resource i`ve discovered.
Common Craft is a two person, husband and wife company. They work from their home in Seattle, Washington. They make videos - short, simple and focused on making complex ideas easy to understand.
And here is a video about the Social Media by "CommonCraft", which I think is very interesting and easy to understand.
You can visit their web site for more videos.
And for those, who are new to Blogs... watch this!!! :)
