I would consider changing your opinion on this; just because you and the people you know use google, a little bit of research will show you how many consumers use default settings of internet explorer, custom installations of mozilla, the AOL browser, or have their settings overridden by plugins like the yahoo search bar.  The numbers are overwealming - how many people don't have any preference of search engine and will enter search criteria into the first textbox they see on whatever homepage some peice of software happened to set for them.

How many cell phones with high speed EVDO internet access do you know that are set to default to google?  How many use MSN or Yahoo?  When a year from now high speed browsers are being sold as standard items in car consoles and they're running microsoft windows mobile or a propriatary GPS software that integrates with one of the other services - how high will your site rank with those other providers?

I've been a long time google supporter, setting it as the default website on new machine installations is one of the first things I do - but you can't assume that everyone uses google; depending on the demographics that you're targeting, I think you will be suprised to find that google serves less than 50% of search queries...  Having seen numbers from drastically different industries (from skydiving to industrial greenhouses); the numbers are quite suprising.

FYI : we do not do anything dnn-specific to meta tags, it's just simply an asp.net server tag, hence it renders an ID tag (so any other asp.net application with server side meta tags would have the same issue). AFAIR you can change  the xhtmlConfomance tag in your web.config to eiither transitional or strict, which will automatically render the meta tag without an ID - though that may effect your skins rendering.

BTW meta tags do not score much in terms of search engines index rankings as they're non-visual so are extremly easy to spam.
