I am currently working on a presentation on data- and telecommunication history and in the last part I dwell on all kinds of online services and give an overview of Web 2.0.

Whilst doing that work, I developed the desire to highlight those services that I really use on a daily basis - and out of which I also get the most benefit, be it in efficiency, entertainment or the feeling that I did something useful. So below you find my personal 23 favourite web applications. Whacky nerdy techy stuff - I know.

And yes - for most of the people who regularly spend too much of their office hours by browsing through the online parts of the local galaxy, the below list might be a bit boring. Sorry for that - maybe there are nevertheless some new things, such as the Hunger Site or LibraryThing.

In any way: Enjoy the summer, spend less time in front of the screen and don't try every link you find in a blog - it only costs time.
