Gnip's jud valeski on Chrome.
My favorite kind of technology is the kind that quietly gets built, then one day you wake up and it’s changed everything. Google Gears has that potential and if Chrome winds up with meaningful distribution (or Firefox adopts Gears) web apps as we know them will finally have mark-up-level access to local resources (read “offline functionality”). This kind of evolution is long overdue. -- Gnip Blog
