Uncommon situations that warrant spontaneous purchases

I’m finding the development of location-based services to be both intellectually intriguing and amusing.  The ThinkNear mobile advertising business endeavor of Telenav intrigues me because I like the ways they’ve grappled with explaining the complexities of geospatial location to business-minded novices. Seeing their current home page ad has been an amusing highlight of my day. Definitely an advertising idea thought of by a man, but I admit it’s clever. Makes me want to send it to my friends and see whether they get it.
