Nine years ago today, the NASDAQ composite peaked at 5132.52, marking the beginning of the end of the dot.com boom. In the year that followed, we bade farewell to the Pets.com sock puppet, those wonderful Webvan groceries, buying a pack of gum via Kozmo.com, or getting fashion advice from the Boo.com avatar. Here's what persevered this week:

• Musical revival: Blowing its doors off their hinges, Yahoo! Music has fully embraced the open web with launch of its new Artist Pages. You'll find downloads from iTunes; albums from Amazon; streams from Pandora, Last.fm and Rhapsody; music videos from YouTube and Yahoo!; photos from Flickr; and tickets from Ticketmaster – for more than 500,000 artists. And you call the shots on whatever modules you want to see. Eventually artists will be able to publish directly into their pages and developers will beef up our modules gallery. Music to our ears.

• Instant iGratification: No need to get all twitchy when you leave your desk -- Yahoo! Messenger is now available for the iPhone and iPod Touch. Released into the wild this week, the free Yahoo! Messenger app can now be found in the iTunes App Store. It's got a lot of the same bells and whistles -- photo sharing, stealth mode, status messages, archiving, emoticons. More here. What?! You don't have an iPhone? Lucky for you Yahoo! Messenger works with other phones, too -- check the roster here.
