Reintroduction of TagWhat

I see that TagWhat, an artificial reality vendor has just reintroduced their product.  Here is their press release   It is delivered via a smart phone and can provide 'stories' linked to any smart phone detected locations.   Get the history, background information and richness of any location on your phone.  An exciting idea, but like many similar AR ideas, requires considerable work to get to a critical mass that will deliver the goods to the average user.   Does make sense at popular travel spots, initially implemented in New York, San Francisco, LA, and Washington, DC.    Take a look at their web site, which has a good video and let me know what you think.  I have it on my iPhone.
