In what looks like a do it yourself mashup solution similar to the Yahoo! Pipes offering, Google is currently running a limited test of Google Mashup Editor where "in a few lines of code and one click of a button you can publish your mashups for the world to see" according to the site.

Google Mashup Editor is an AJAX development framework and a set of tools that enable developers to create web applications with Google services like Google Maps or Google Base. It will provide an easy to to utilize information from feeds and let users see and manipulate. Most interesting to me is that GME will be using technologies most of us are at least in part familiar with - XML tags, JavaScript, CSS and HTML. It could be a major step up from Yahoo! Pipes which I have spent quite a few nights with over the last month or so.
