Do middle aged women read blogs?

I'm working with the American Heart Association with a web content migration for their new website.

They are using a CMS Content Management System to help deploy their new site. To help their end-users with training I prepared an email blast with tips ranging from how to search for content, shared examples of good graphic examples, pages and widget others in the company had created in the hopes of getting them motivated by sharing and learning from others.

I felt that an email blast would best target those creating the content and using their CMS to migrate the content.
However I'm not the boss of this job by any means and can only make suggestions as I'm considered simply an outsider on this.
So it was decided to upload this tips to the design teams blog. Easy enough I guess but my lingering though is will it reach the intended audience? Do middle aged women read blogs? Do they read technical blogs?

Look for the new American Heart Association website in early June 2010.
