Mobile marketing will be getting more and more important as Internet connectivity become ubiquitous. Imagine being in a city and not knowing where to go get a bite to eat with friends. You pull out your hand held computer and ask it to pull all the restaurants within a 5 mile radius of where you are. Then you can check your social network to see if anyone is currently at any of those places, read their past reviews, look at real time streaming video inside of all the different bars to see which one has the best vibe and see if any of the restaurants currently have offers or coupons they are sending out. It will be something like this eventually. Mashable had an article about Coupious:

delivering on-demand, location-based coupons to smartphone users for savings at the point of sale. Coupious works by using your phone’s GPS to provide location-based coupons relevant to your immediate whereabouts. Essentially, all you need to do is launch the application to find deals within walking distance or up to 50 miles away.

There are so many cool implications with mobile internet. I had an idea once to make a site that shows where all the best skate spots were so if you were in the city you could look at your handset and see the closest spots to where you were. And then I found out that subpublic.com beat me to my great idea. Although the problem with the idea is creating incentives enough to get kids to upload skate spots. Do a search on Denver and there are no spots uploaded.
