Del.icio.us could be extremely useful for his business. Wiredset helps entertainment companies develop their digital strategies. By following the tags for a band, Ghuneim could let a record company know the level of buzz after a radio interview or live performance. He could find chatter about budding artists. Essentially, del.icio.us would allow him to listen in on the conversations on the Net that he cared about, minute by minute. He's now obsessed. (...) companies are figuring out ways to take advantage of this phenomenon. As they tag, subscribers end up collectively highlighting changing trends and raging discussions all available at the del.icio.us site. Increasingly, innovative advertisers and other companies are trying to make sense of these discussions. "The conversation we're having with clients is, 'How do you stay on top of tagging? Because you need to, and it can be hugely beneficial,"' says Dan Buczaczer, a vice-president at ad firm Starcom Media Vest Group. (...) Wiredset is on the leading edge. It's developing a service for record labels that pulls together a variety of online data -- sales on Amazon.com, number of blog posts, tags on del.icio.us. The idea? Allow labels to see, in real time, the impact of their marketing. If Sony BMG Music Entertainment releases an MP3 from the band Franz Ferdinand on MySpace, it can track the buzz. Or watch how an MTV video affects Amazon sales. As a test, Wiredset is tracking the tags of a London band, Bloc Party. Wiredset follows the chatter around the band's new album to pinpoint influential online players. "It's good to find and establish relationships we might not know about,"

Why do I blog this? It's interesting to see how a field of digital marketing emerge based on Web2.0 applications (technorati, del.icio.us...). Besides, my favorite part is when they say "It's good to find and establish relationships we might not know about," because it's really what I like to do: finding and understanding connections between different concepts.
