This is a cool site that allow you to have a collection of your favourite sites on the front page as quick links. Simple but effective. However, I am not entirely sure how it is better than others of a similar ilk. It does talk about having one's own site and sharing including through social networks. Maybe it is the sharing that makes the difference. Also, they say there are lots of widgets for news, weather, games etc.
And the name? They say it is pronounced "start", the "h" replaces the "a". Not too memorable for a dyslexic! But then it is supposed to be one's home page.
