I'm not sure about this particular situation. I would imagine that other players would call the shoves with weak hands for the same reason as you're shoving.
There's an amusing video of Gus Hansen shoving all in blind for about 20 hands in a row where he was in a tournament league where he had to come first to get enough points to qualify for the final. That strategy worked because his opponents couldn't afford to go busto. (They had to finish in the top 3 or 4 to qualify). Hellmuth called one of the early shoves with AJs, and lost to a set, sending him on one of his trademark tirades. http://www.youtube.com/watch?v=Gq3zZbj8TDE
