Dapper is the newest of the tools I’m looking at today. I first became aware of it via a rave review on TechCrunch. Dapper is a tool which allows you to create an API for any website, and then combine it with other of these APIs (called “Dapps”) to build applications.
This is a very interesting tool: the ability to create APIs easily is a wonderful feature. It doesn’t yet have the ability to do “spreadsheet-like” features like adding columns of data, though.
