The first startup funded by YEurope (http://yeurope.net/), a YCombinator (http://ycombinator.com/) inspired (not affiliated!) hatchery based in Vienna, Austria, just launched their public beta.
Soup (http://soup.io/) is a mixture of a tumblelogging and lifestream aggregation platform. Soup simplifies publishing a stream of content by reducing mental overhead and removing barriers found in traditional blogging software.
Soup allows users to both post microcontent and aggregate their digital presence from other web services using RSS feeds or a bookmarklet.
While the lifestream aggregation arena is quickly becoming crowded with competitors (most recently with the launch of Paul Buchheit's (http://paulbuchheit.blogspot.com/) friendfeed (http://friendfeed.com/) on October 1st), Soup competes strongly with a broader scope and a refreshingly simple, Ajax-driven user interface.
You can start using Soup right now at http://soup.io/ -- no sign-up required.
