Thanks to Mara I’ve discovered this nice website, http://musicovery.com/, where you can choose the music depending on your mood (more or less energetic, positive, calm or dark) and also based on years… In few worlds this “simple” application is matching the metadata of the songs with your choice…
Web 2.0, semantic web, nice.

Ah of course is yet another beta, indeed! 2.1!

I call it juice. When the effort is really minimum (i.e. you don’t waste more than 5 minutes, you click only 2-3 times) and you produce something like this:

This is Web 2.0 Juice. I’ve installed some time ago the iScrobbler app on my Mac, now I’m happy to share my listening on last.fm. [hei windows user, don’t worry, looks like there’s also a client for windows…]
What other Web 2.0 Juice? Flickr, I love especially the “send to blog” functionality: very easy and immediate. I like a lot Gmail and I use it a lot, with Mac Mail, from the web, from wap, from their good MIDlet.

I still didn’t found any other so good service like the above ones and since there’s no sharing/communities ideas behind Gmail the good 2.0 juice are only last.fm and flickr.

DailyLit is a service that sends you an email with a paragraph of a book that you choose at the time you want…

Build Your Own Web 2.0 Application Using Fluff and Hot Air
So you have a great idea that you want to turn into the Next Big Thing? Well, jump aboard the Web 2.0 bandwagon! The momentum that’s building behind web applications means there’s never been a better time to start reaping the rewards of your hard work.

Wait! Hard work? Not interested in hard work? Don’t have the time to put in all those late nights fixing bugs and adding killer features? Then this article is for you. We’ll show you how to go from idea to well-funded application without writing any code at all.

Thought that all you had to do was add “Beta” to your product for it to be successful? Not true! In today’s climate it’s possible to arrange first-round venture capital funding and get your flavour-of-the-month web app snapped up by Yahoo! before you even reach beta.

We call this Getting Rich.
