Is blogchalking useful? When some weblogs are collaborative and international (remember Eurotrash?) and some other blogs are written by expats (we have had so called GBlogs that have Aussie, Dutch, Kiwi and Irish authors, for example), is categorising a blog by the location of its author any use? Even for British blogs written by British passport-holders, the content is often not location-specific, and in fact the location of the author is irrelevant.
So why blogchalk?
