Inventory????

Well, here it goes, though I don't know exactly what is expected. I will go by the definition.

There is a dashboard that serves as a home base so that you can go out into the blogging world you have created.

There is a layout so you can make it personal. You can add widgets from other sites and so forth.

You have your profile in which you can share as much or as little as you wish.

There is a place to post to any or all blogs, which is just adding your content.

You can add pictures, videos and audio.

In blogger, it automatically creates an rss feed so you can link it to an aggregating device, then you can sign up for automatic updates by choosing a disseminating device so you can listen to what YOU want WHEN you want.

Of course, you have your advertisements, which you can get out of, in your settings.

That is my best guess at a blog inventory.
