I do presentations all the time about blogs and social media.
In fact, next week I will be talking to a bunch of executives about why they need blogs in their organizations.
Since I only have 30 minutes, I am breaking it down into answering the 7 most common questions I get, and inviting them to follow up with me after.
Since I have been trying to improve my video skills of late, I did a shorter version of the presentation. If you are on the fence about blogging, watch this presentation. It should answer your questions and be realistic.
