Are Liszen the new Digg?

Having already spoken about Liszen (which describes itself as 'connecting you to 500 plus blogs within the library profession). On a new article on Library Zen (Garrett Hunford's other site/blog in conjunction Liszen) called
LISZEN: Submission, Recognition & Trends (OH My). Garrett is doing an excellent job, and has brought forward the idea of :-

'LISZEN: Trends (The Best for Last)

LISZEN is more of a library community archival tool than a source for new information. So why not create something that allows users to submit and vote on content in order to create a real-time/social library tool? That’s were LISZEN: Trends comes into play. I spent last weekend tweaking LISZEN: Trends and want some user input before it’s released. On November 22nd at 5 p.m. [EST] a form will be posted allowing users to request a sneak peak. You will have until midnight on November 28th to play with the site and follow a small set of testing instructions.'

This usability feature seems like Kevin Rose's Digg site, which is described as :-

'Digg is a news website with an emphasis on technology and science articles. It combines social bookmarking, blogging, and syndication with a form of non-hierarchical, democratic editorial control.'

This reminded me of another description of what Garrett MAY be doing. This is what wired has termed meganiche, described as:-

'Meganiche sites are often based on a mainstream topic, but they carve it into divisions that the market as a whole may barely recognize..........User-generated content is the Web-biz buzzword of the day, and meganiche sites tend to produce lots of it.'

Whatever label it is, this new idea sound wicked.
