just 4 to 5 days ago i read on Google official blog that they have change some thing and it will be more difficulty to finding to get result. I don't think so that you need to change much in your style just stick to your basics here is the details http://googleblog.blogspot.com/2011/02/finding-more-high-quality-sites-in.html what do you say about this
well just the introduction said: "Our goal is simple: to give people the most relevant answers to their queries as quickly as possible." so this update is good for their user.
I say it's about time. I was sick of Google showing crappy websites that just mash up articles or still content.
The problem with the new algorithm is that in the period of consumer meeting many sites support the contents created by user that reduces quality of contents of the site. Due to this the site may drop in traffic or decreased in traffic.
Good quality content always won the day and it will still win. Stick to "content is king" and you don't have anything to worry about.
