Google has announced in the Google Places Help forums a new video they posted using Google+ Help Desk Hangout On Air to answer questions about Google Maps and Google Places.

Here is the outline followed by the video:

0:45 – What is Google Places for business?
1:31 – How a user sees business information on Google
9:22 – Adding your business information
13: 35 – How any user can help us keep places information up to date
17:58 – Top Contributor Jack joins the Hangout! (Some tech issues here.)
22:46 – Joel and Jack answer your questions for the rest of the hour, including: ranking in search results; marking a business as closed; ‘at a glance’ terms; best practices for descriptions and service area businesses; and more!

It is a bit shaky at start but ends well.
