InformedNetworker.com - Digg for Network Engineers

InformedNetworker is a social news network site modeled after Digg (but officially using the Digg-clone application Pligg) for those working in the computer industries. It covers a wide variety of topics including industry news, development, software, hardware, security, storage, servers, internet, etc. It tags and categorizes stories, and lists out the most popular stories of the day. It also has a section for reader comments on stories, which probably adds value and interest to those working in the industry (i would imagine that many stories of new products and technology generate lots of gossip and tidbits that networking professionals want to discuss).

"A social news network for network engineers."

I am a fan of niche sites, and this is a niche Digg-type site. The site seems to successfully cater to those in the computer industry, as all articles revolved around that topic, which I believe may be quite useful to those in the field.

Do people use niche Digg sites or just go straight to Digg and search for relevant stories? Given the low traffic volumes, how have they tried to drum up readership? Are their other, more popular industry-specific web sites that is slowing the growth of this site? I might also add that the design and color of the site were definitely unappealing. How do they hope to make a profit?
