Mark NYC--there are a number of Marks on this site. Certainly those of use affected most by the spill have a great interest. If you had read all of my comments there is note of the various outer companies involved. People make a not of unfounded assumptions based on the blabs on TV and media. There is no question in most people involved in the industry that the most important issue is to stop the spill/collect oil and prevent further spread.
As for seepage vs the spill, again it is concentration. The seepage occurs over a fairly large area, and a large amount of time. Oil on the beaches has been a way of life in Calif. for many decades--long before drilling. My grandmother had oil seeping up in her back yard in Long Breach, CA for years, She also received royalties from the time the first oil wells were drilled in the area. This home was at least 100 feet above sea level (even after subsidence due to oil removal).
Marc--none of us know what the future holds for the Gulf's wild life. We do know that it has been heavily overfished--there has been prior massive polution--(Rivers, agriculture, industry). You mentioned Corexit. We don't know the full effect of it--but there is a huge dilution factor. The amount of dispeinrsement is somewhere more than a million gallons. A cubic mile of sea water contains over 10 to the 18th gallons of sea water. There are over 600,000 square miles of the gulf, and the average depth is just under a mile. So the amount of dilution is immense. You noted that the reef might be under more stress because of dispersements, and oil, than the swamp. However, I neglected to mention that there were many gallons of pesticide, oil, paint, and sludge from the aforementioned paper mill (whose river produces 2 headed fish etc) Marie and I pulled many empty containers out of that area--so I suspect that the stress on the swamp was more than an open water reef. The point was that there is immense restorative power of Nature.
I have spent the last two days with scientists in Texas who are working with the University of Texas, and there are a number of innovative "solutions" which are being proposed. There are over 150 people just at this institution working on the problem--not hired by BP or the government.
We have to keep all of this in prospective. Although this is an immense ecological disaster, there have been far worse. The environment has recovered.
