Completely "Lost"

After watching last night's installment of "Lost" on ABC, I have two comments:

1. Thank you to the local ABC affiliate (the great WFAA Channel 8) for not breaking in to the show to give us updates on the Apocalyptic thunderstorms that blew through D/FW during the program.
2. What the HECK is going on?

The show is off to a solid start for season 2 and, while some things have been sorta cleared up (it WAS The Others who nabbed Walt, not a bunch of South Pacific pirates; Charlie is not over his heroin addiction; and Locke has a knife for every occasion), the big mysteries are as muddy as ever.

And what on Earth is that logo that appears on Desmond's shirt along with the contents of the Costco-like storeroom that Kate found herself in, and, apparently, the shark?
