It's probably because Death Note is one of those 'popularized' anime. Lots of people who don't bother DLing/buying other animes watched it on Cartoon Network. People who have a limited anime experience most likely know Death Note. Same goes for Bleach, Naruto, One Piece, Code Geass, Cowboy Bebop, etc. They are all animes available to the mainstream and therefore you'll see tons of people recommend them because those are the only ones they know.
Not saying they're bad though, Cowboy Bebop remains to this day my favorite anime series of all time, and I've watched over 250 anime series.
