No offense Ike, but I don't think you know what you're talking about. Sure it's just an oil spill, but the oil itself isn't the problem, it's the side effects (if you want to call them that). Sure there is a large amount of water compared to the oil, but that doesn't mean it's not noticeable. The oil is still spilling at thousands of barrels per day, we still have at least two months left of this, and that's if the solution even works.
It's not as simple as getting a bunch of ships and dumping chemicals/burning up the oil (just doing that takes reasonable effort), this is an enormous area. Also, most people don't even know how to deal with this, all the relief efforts are not coordinated with each other, and their individual impact isn't much anyways. The oil is destroying part of the environment that took many years to take shape.
Also, as others have said, many people's lives are being ruined by this. They're unable to make a living off what they have been doing for generations, and they can't just move, their families and equipment are in the area. I'm sure there are even more concerns, such as the type of fish in other areas, plus new regulations that their companies would need to adjust to, and just getting a new license.
Besides just the fishermen, many cities along the coast rely on tourists for their income, and with the attention the media has been giving this, not as many people will be visiting the beaches along the gulf this summer. That's another thing, the cities themselves can't move, they're basically screwed. The beach I was at a few weeks ago has tar-balls washing up on the shore, so much for the "whitest" beaches around.
And of course, BP themselves is suffering from this, they are getting a lot of bad press, and they're spending millions to try and fix this. Also, anyone involved in dealing with this probably has had a headache for the past two months.
Alright, so taking all of this in mind, how do you not think this is a big deal?
