Works in progress

During a corporate website presentation, an ICYGEN employee asked the following question:

Websites are supposed to be completely revamped every 3 or 4 years. Minor changes to websites should be implemented once every 3 months. How do you think your corporate identity will be affected?...

In my humble opinion, and please do correct me if I'm wrong, the above question is pretty stupid. Change your website once every 3 months?! Dude, do THAT and you will have a total of 100 visitors...A WEEK!!! The ICYGEN update rule might have been valid back in 1998 when people used to create static corporate presentation websites that never changed and then, quite understandably, just died. That, however, is clearly not the case in the era of Content Management Systems, blog-tools and the like.

Anyway. What I wanted to ask was your thoughts on the opposite phenomenon: websites that constantly change. And by change, I obviously mean changes different from adding new news-items, blog-entries, or client-profiles to your site. How do you feel you about that? How do you feel about people/corporations adding new sections or changing the structure of their website under the pre-text of 'developing their vision' or whatever.

I am aware that the most accurate answer to my question is It depends. Of course, there are different ways in which one could implement change. But, I still would like to know where you draw the line between 'work-in-progress' and simply 'never-getting-it-done'.
