Specifically, Transpose. Here we have a really attractive online tool for sticking structured notes in the cloud. "Structured", here, means typed fields that go into something in the back office that can be searched by type. Notes are also typed in that they are arranged into templated lists; each template has a set of typed fields. If my template includes a date and a location, for instance, I can look for all notes within a mile of a given set of coordinates, plotted on a Maps window.
That is pretty freaking excellent.
Transpose the business is a freemium model that incorporates crowd sourced templates in its "public library". That allows you to leverage some level of information about how other people do things. That's pretty freaking excellent, too.
The free version permits up to 10 templates.
Your mission, if you choose to accept it: write a sketch of the system and the business in Decl. Work on the semantics behind the scenes to make it a reality.
