I just looked at your submission history again and even the most recent one "Game industry of Finland" on slideshare is marked [dead].

Looking back through your history, the last 129 submissions are all [dead] it changed right between #129 and #130.

Your #130 was "Startup - Bill Watterson, a cartoonist's advice" which got 192 karma points, but starting with #129 "Brilliant Resource on Typography (practicaltypography.com)" posted one day later, everything is marked [dead].
