Organise your readings
Totally thrilled by Bloglines at the moment. Apart from being multi-lingual and doing blog searches, it also lets you have a free blog (no ads!). But the subscription service is a real time-saver. Customize all your favourite reading sites and have them beamed over as RSS to your blog or a special email.To be able to make clippings from the feeds is a great idea.The service is for free searching, subscribing, creating and sharing news feeds and blogs.

Virtual Earth tool
Tagzania is about tagging the planet. You can create and document your spot or any interesting bits of the planet via tagged Google maps. This folksonomy via collaboratively shared space-time is worth a watch. Germany and Berlin seem to feature very strongly. Australia is, as so often off the map. Their blog gives you more info. Great tool for landscape mapping too.
