great input and much appreciated.
Ideally i would like to have the blog moved over, but there is a lot of links/content to deal with. I'm working on developing several content gen strategies, and wanted to make the blog a part of that. Currently it's always been more a part of the social media efforts, but work has been done to better connect it to the main site and make sure it's branded to be one in the same.
Where i'm a little unclear is the tech efforts of doing this. I would assume as thomas mentioned it's a matter of creating the subfolder to house the wordpress install/content and setting up a 301 on the old domain, but the need to do each post individually is where my concern is.
