Some have suggested deleting your meta keyword tag altogether.
I don't see the value in "going commando" just for the sake of it. Indeed many of the sites that are now on the first page for my targeted phrase have a well-stuffed keyword tag. What I've chosen to do is reduce the tag content to a single word or two-word phrase that succinctly describes the page.
To take a made-up example, if the page is about "Underwater Exploration" I would use that as the tag and remove references to "Submarines", "Snorkels", "Scuba Diving" etc.
