1) How you use PostGIS?

I'm using it as a backend database for our GPS track sharing site http://timatio.com/

All the GPS data that users upload is stored in PostGIS - very useful for finding relations between different tracks, calculating length, intersection with countries, etc, etc.

Other features from PostgreSQL itself also come handy, like the full text search module.

2) What you find useful about it over anything else?

It's simply the best available spatial database system i know of, has an active development community that is not just helpful, but also eager about bug fixes.

3) Why you think there should be any book written focused on its use and of
course if such a thing were to exist, would you buy it?

Location data is becoming more and more important - and even though the general management of databases is assumed to be common knowledge among developers, managing spatial data is still a niche that is bound to go mainstream.

(if you use that sentence in the book, i want a free copy ;)

I probably wouldn't buy it, because i have a couple of years of experience with PostGIS - but, that might of course depend on the focus of the book.
