As I've observed before, tech buzzwords that escape into general usage tend to lose their semantics at the hands of wannabes and the media. Commendably, an article at Ars Technica not only notes the phenomenon as it applies to 'cloud', but does something about it by recounting the history and actual meaning behind the term. (And yes, this is another example of the new media kicking the MSM's behind.)
And I should also give further credit-where-due, in noting that Ars has become one of my favorite feeds, due to its willingness to sponsor in-depth pieces, rather than the regurgitated press releases or shallow reviews of the product du jour that prevail at other outlets. Further case in point, this ongoing series on genome sequencing. Well done!
