If LA is talking technical stuff, I would say it would be fascinating radio. If he's shooting the breeze and talking about anything other than training, I'd think it would be a yawner. Dood is not very articulate.
XM will never merge with Sirius. Sirius is a losing venture overall, with all the celebs and the crazy contracts they've been passing around. XM is the true money making profit venture, and if you compared the two, you'll find both of them state that they've produced profits. Unfortunately, if you subtract out the money from the contracts, you'll find that Sirius is losing money, while XM is not. From what the business pages say, Sirius will continue to lose money, and within 5 years, maybe they'll be out of business, unless they can come up with some other way to earn the money they lose with contracts. So I hope Lance enjoys the show... chances are, it wont be around within a few years.
