Item 14
Using Technorati I looked up 'Learning 2.0' using a Blog Post search and found a huge number of items. The Tag search produces fewer items and included visual media such as videos and pod casts. Probably the most useful search was the Blog Directory search which led to less items but which seemed to be the most relevant.
I was not surprised by the most popular blogs, searches and tags, the subjects of which revolved round popular culture and technological advances.
The advantage of using tags is that they are accessible to all, no special vocabulary or indexing system is needed and as language and terms change so can tags. This characteristic can also be seen as a disadvantage, as having a universal classification system into which all material is fitted can lead to a more complete retrieval system when used expertly.
