Whether you're a blogger or a reader, this is an interesting interactive image - a blog road map, if you will - from Wired magazine. Trace the route of a blog from writer to reader - and everything in between. If you've ever wondered just what a text scrapper, ping server, or aggregator is, get a little explanation and see where they fit into the information superhighway.
I wonder how many of these elements student bloggers (or teacher bloggers) are aware of? How would their writing be affected by a greater understanding of this map? My initial reaction is that if students really knew that the online words they write would find their way to search engines, or that depending on the content their words might be seen by corporate representatives - for good or for ill - how much more care would they take in writing and proof-reading their own work and the work of their peers?
