Does google know too much about wordpress?

First off, I'll say I love wordpress and I really push my new clients to utilize it in some way since it's so user friendly.

I'm concerned about how big WP is getting and how smart google is when it comes to checking out these sites. WP says it powers almost 15% of the top million websites, so it's a big deal.

On my google webmaster tools panel I'm constantly getting information about how I should update my WP installations and specialized messages for wordpress.

Googlebot obviously knows its way around a WP installation and it might increasingly know what's up in terms of your marketing activities. The good thing about this is I don't think google penalizes as hard for 'appropriate' dupe content on a WP install, such as archives, category pages, tag pages, etc.

On the other hand, I wonder if there are any downsides to google knowing so much about someone's website. It's obviously not as much of a risk as using google analytics (which I use for most of my sites anyway), but WP is constantly developing new features that googlebot could eventually use to gain 'unwanted' insights into your site.

At this time I don't think it's a big deal at all, but I'm definitely keeping watch.
