It was probably actually more the FANS of Howard and O&A that bickered then Howard and O&A themselves. There was a time (back in 2006 when Howard first came to Sirius) when Howard fans and O&A fans were at each others' throats on message boards. O&A fans would start posts about Howard with "Hoo Hoo Hoo Hoo Hoo", because they called him Hoo Hoo Stern, and Howard fans would in turn call O&A "Stren wannabes". O&A pests would show up at Howard's public appearances with signs. I can see that it is not like that anymore, five years later. But if you consider O&A and Stern themselves, O&A put down Stern a good bit on the air, while Howard rarely ever mentioned O&A. I think O&A felt threatened by Howard's move to satellite back then...but now that it's been 5 years, all that has calmed down.
