Echo location
This seems to be a great idea:
Matt.Blogs.It What I want is a zip code / latitude / longitude / gps coords that can be applied to a single post. Why? Because blogs are a great way to capture off the cuff knowledge, feedback, etc. Long time readers may recall my troubles with the furnace in my current residence at 124 Langley Road in Newton MA. What I’d ***love*** is the ability to (in a standards compliant way) tag my blog post with this data. Then some future poor sod who rented this place could take advantage of my troubles and ask intelligent questions like “Fixed the furnace yet you pathetic excuse for a landlord”?. As blogs become less and less about purely digital stuff and more about the real world, this is increasingly useful.
Just imagine: an easy way to know what was that strange noise you heard coming from your neighbours 
Of course we already have GeoUrl but this would work on a per post base and that could make all the difference.
