Ok, let me rephrase that. The SE's that bring 95% of Web traffic to sites do not use them. There are likely hundreds, maybe thousands that do read them (not use), but they are still superfluous and VERY few people in comparison in turn use these 'other' SEs.

I highly doubt any SE, that people use, "rely" on them.

I beieve most se se meta tags for thier Listing informaton bUt not for ratings. With that said meta tags stiLL are an important aspect of seo....

anyways, why post to bash? dont instaLL it if YoU dont think it does anything...

Sorry, didn't mean it to sound like a "bash". It's just that there is so much bad & misinformation out there in regards to SEO.

Seriously, the only Meta tags that matter are;

Meta Description
Meta Keywords <many say these are totally ignored>
Meta Robot. E.g <Meta Name="Robots" Content="NoIndex">
