From a Search Engine Land Post by Greg Sterling:
Microsoft has introduced a number of improvements to Bing Maps, chief among which is making “venue maps” more obvious. Microsoft says there are roughly 900 venue/interior maps on Bing focused primarily on “malls, airports, casinos and shopping districts.” Google has a similar initiative but it’s focused on Google Maps for Android for the time being.
Sterling’s article continues with a look at each improvement (w/ screenshots).
