More new features from the Posterous team - Google Maps integration. Just paste a link and it embeds a map. I need to test this from the iPhone next since it also works with geo-tagged photos too.
Thinking about how this might be used more broadly beyond posting. What immediately comes to mind is search. Show me all Posterous community members who have uploaded from the following areas in X hours. Also hoping that as video gets more metadata, we'll see more hyper locally tagged embeds too.
The map below should show you where I am in Chicago. I found myself using Google Chrome on my netbook and then copied and pasted the link into the email. Nice feature!
