"Xenu's Link Sleuth (TM) checks Web sites for broken links. Link verification is done on 'normal' links, images, frames, plug-ins, backgrounds, local image maps, style sheets, scripts and java applets. It displays a continously updated list of URLs which you can sort by different criteria. A report can be produced at any time."

"According to the 'long tail' principle, ICT innovations in content creation and distribution such as virtual inventories, Internet Protocol Television (IPTV) and other types of video on demand, music self-publishing in social networking sites and digital printing challenge old rationales that justified the adoption of mass-market models for the production and publication of cultural goods. These technologies dissolve the spatial and physical constraints which limited the range of creative content goods available in the market and open the gates for a flood of new (and old) media. In doing so they have created a new problem, of a navigational nature: in principle, diversity enables access to content goods better suited to a customer's preferences, but it also makes finding them more difficult (194).
The main reason for the success of Google's search services has been its ability to address Internet users' need for relevant resources, by adopting a scalable algorithm that establishes a webpage's rank according to its reputation. However, its user interface is still too rigid and makes it difficult, for example, to fully specify the type of content a user is looking for. Additionally, this technique, based on a 'Wisdom of the Masses' perception of the web, can in some cases promote content perceived to be useless over content perceived as useful, and be tampered with through search optimisation techniques such as link farming (195)."

194: In a context where information is abundant, attention becomes the scarce resource (Simon, H. A. 1971, 'Designing Organizations for an Information-Rich World', in Martin Greenberger, Computers, Communication, and the Public Interest, Baltimore, MD: The Johns Hopkins Pres).
195: i.e. exchanging reciprocal links with web sites in order to increase search engine optimization, as search engines often rank sites according to, among other things, the quantity of sites that link to them.

"Critics such as Andrew Keen argue that Web 2.0 has created a cult of digital narcissism and amateurism, which undermines the notion of expertise by allowing anybody, anywhere to share (and place undue value upon) their own opinions about any subject and post any kind of content regardless of their particular talents, knowledgeability, credentials, biases or possible hidden agendas. He states that the core assumption of Web 2.0, that all opinions and user-generated content are equally valuable and relevant is misguided, and is instead 'creating an endless digital forest of mediocrity: uninformed political commentary, unseemly home videos, embarrassingly amateurish music, unreadable poems, essays and novels,' also stating that Wikipedia is full of 'mistakes, half truths and misunderstandings'."
