Web 2.0 too much?

Can a world which constantly updgrades itself - Internet Explorer 6.0, Windows Vista, Microsoft Office Suite Super-Duper Maximum - ever reach a saturation point? Teacher Librarians are encouraged to use Web 2.0 tools to exhibit their communication strength and technological collaborative capabilities. But are we going overboard and risking the basics?
For those not quite sure of Web 2.0, Tim O'Reilly provides an awesome comparison:

Web 1.0 *** Web 2.0
DoubleClick *** Google AdSense
Ofoto *** Flickr
Akamai *** BitTorrent
mp3.com *** Napster
Britannica *** Online Wikipedia
personal websites *** blogging
evite *** upcoming.org and EVDB
domain name speculation *** search engine optimization
page views *** cost per click
screen scraping *** web services
publishing *** participation
content management systems *** wikis
directories (taxonomy) *** tagging ("folksonomy")
stickiness *** syndication

The key to understanding Web 2.0 is the difference between publishing and participation. But what Jakob Nielsen is trying to get us to understand is the difference between new gimmicks and quality priorities. His remarks focus more on business websites, but are certainly applicable to teacher librarians and technology advocates trying to infuse the latest and greatest into everything they do. Nielsen sees

"the rush to embrace Web 2.0 technology meant that many firms were turning their back on the basics ... The idea of community, user generated content and more dynamic web pages are not inherently bad in the same way, they should be secondary to the primary things sites should get right."

No matter our progressive intentions to include information technologies in our profession, forsaking quality defeats the purpose.
