Do you think that social bookmarking is over the top?  Does it bother you to see multiple social bookmarking links like Furl, Simpy, Technorati, etc. on web sites?  Why or why not?  I’m interested in seeing what people, both tech-savvy and tech-challenged, think about them now that they’re more popular, and how such technology is changing the way users are seeing web applications, products, brands, usability, functionality, marketing, and so forth.
