Wanted to share a plugin we just launched with the community.
The Placeling plugin lets you tag a location to your post and then your readers can see nearby posts via their iPhone.
For instance, if you're a food blogger, I can see nearby restaurants you've written about while I'm out in the city. (Plus, I'm reading your blog post about it, not going to Yelp or some other source).
Plugin is here:
More details on how it all works is here:
Happy to answer any questions anyone has.
