I have seen and experimented few results and came to know that the title tag is very important and should be unique in the website, do not stuff keywords in the title tag, any comments?

But, I don't think that stuffing keywords in the Title tag has affected any websites. I daily see lots of web hosting providers in search results where they have stuffed targeted keywords in the Title Tag. However, if you want to improve according to Google's changes, make sure to read the updates on their Official Webmaster Central Blog.

Title is Vital to your SEO Efforts. Each Page need to have a Unique Title that accurately describe the content containing in that pages.
Reason : Page title is important because this is what will be displayed in the result section of search

Title is display at the top of the browser window. Title tag is the most important factor for any Website because it is first factoring which is seen by search engine Spiders but rather than only stuff keyword in the title tag it is beneficial to create effectual title which include keyword in it.

Google is making a change to its search algorithm to penalize what the company's head of Web spam called "over-optimization" and instead favor websites with high-quality content and less refined search-engine optimization.
