Google 'gaming'

Changes are taking place in the world of Google, now they are looking at how they can improve on 'apps' that give local information. I have come across reports about apps that can identify pictures taken from a mobile phone camera. The app can recognise a logo, shopfront or landmark and give search results relating to what it can 'see'.
This is a tremendous leap forward in how Google can continue to help people to find what they need, but it has caused a stir amongst webmaster and journalists that are concerned with writing about SEO. However, my take on it is that really it is up to Google to come up with a way to integrate the information that is already there, so in the long term, webmasters are not required to jump every time Google comes up with a new concept or search hysteresis. It seems to me that webmasters are in danger of forgetting that Google has a clientele (primarily the technology-aware general public) to serve and therefore have a duty to bring your website to the attention of their clients where relevant. The idea of gaming the results to get yourself in a high position regardless of relevance is a short-term tactic. For those in for the long-term, my advice is to keep on doing what you are doing and let Google worry about getting your site into the search results - there is still no replacement for good content although there are naturally small things that you can do to make sure your site is optimised. Optimisation is still based on the basic tenets that it always has been, with noticeably less emphasis on PageRank (off-page optimisation), and more emphasis of the following on-page tactics:
Content, content, content - unless you are planning a landing page only (shame on you...), you should really spent the majority of your time on producing good content. I wouldn't even be overly concerned about keyword density because if you write naturally and informatively, your keyword content should be naturally correct.
Tags - it is so simple to add title, alt, keyword and description you would have to be crazy not to do it despite the fact that it is not considered 'sexy' - you would be far better employed doing tags than designing a flash animation for your visitors. It is still a webmaster crime of epic proportions to have a page title come up as 'home', 'index' or 'untitled' no matter how good your page looks if a visitor ever actually found it.
URL's including keywords - still a winner for search results and will continue to be - any page that does not have a keyword in the URL may be a page wasted.
As long as the oh-so simple rules of on-page optimisation are behind what you are doing, I believe Google is obliged to seek you out and put you in the search results... THAT after all is their job, it is not as many believe, Google's job to 'police' the internet.
