Presenting compelling search results depends critically on understanding what is there to be presented on the first place. Given that the current generation of search engines have a very limited understanding of the query entered by the user, the content returned as a result and the relationship of the two, the opportunities for customizing search results have been limited.

The web 2.0 concept is not sufficiently defined to allow a critical discussion of it, but we can discuss AJAX (asynchronous Javascript and XML). This concept, which underpins many web 2.0 sites, repackages and applies existing technologies to achieve a new structure for internet applications. Unfortunately, increased flexibility creates conditions for new security problems.

To understand how AJAX alters the security landscape for web application testing it is necessary to show the fundamental differences between it and traditional internet application models.

• The need for Ajax fingerprinting and content filtering.
• The concept of Ajax fingerprinting and its implementation in the browser using XHR.

Whilst a number of methodological and philosophical difficulties surround its definition, ‘informal learning’ is now acknowledged to be a vital element of education for learners of all ages (Colley et al. 2003). Despite the ‘slippery’ nature of the concept (Girod 1990), there is an emerging consensus that the nature of informal learning is more specific than simply being any learning outside of formal education. At one level informal learning is “undertake[n] individually or collectively, on our own without externally imposed criteria or the presence of an institutionally authorised instructor” (Livingstone 2000, p.493). Thus, whereas formal learning is typically institutionally sponsored, classroom based and structured, informal learning “is not typically classroom based or highly structured, and control of learning rests primarily in the hands of the learner” (Marsick & Watkins 1990, p.12).
