With our Guest Steve Hargadon. Steve shares his insights about tagging with us.

Our discussion included use of tagging in blogs, pictures, in social bookmarking, at conferences, and with our students.

Steve talked about the purpose and structure of tagging. We use tags on content we produce so that it is useful to others on the net. The use of tags in social bookmarking such as del.icio.us and diggo are examples. We are able to see how others tag content on the web. We can tag our own content using similar taxonomy or create our own. Steve reminded us that there is tension between using standardized tags versus a more independent free flowing tag system. We can use technorati and or Blog search engines like google to make sense of all the content.

At NECC 2007 session specific tags were proposed and adopted by the community. This standardized form of tagging allowed for aggregation session specific content. The same system is also used in classroom 2.0 to standardize the way blog posts and other content is tagged.

Our next show will be on January 14th, 2008 at 4:00 p.m. Pacific / 7:00 p.m. Eastern. at Edtechtalk
