Meta tags are somewhat important, but I would focus on backlinks and optimized copy. I attended an online BlackBerry training class and that is what they covered. It was great.
I have read the same from some of there supposed senior reps.?
Hard telling, they change there format so often.
I wouldn't forget about meta tags though....there are a lot of other search engines out there that still use em.
Not to mention, HUMANS read them when you do show up. So your meta tag may be the deciding factor when it comes to humans clicking on your link on someone else's. So while the engines may not value them as much for rankings, humans value them.
