My favorite feature? When you highlight a word on any page a drop down menu automatically appears (see image below) that lets you:

• search for the highlighted words on the web with any of four search engines
• search for highlighted terms in four social bookmarking systems
• do a blog search for highlighted terms
• search for your terms in the entire site you are on (Google, Yahoo, Ask site: search)
• search for inbound links to the URL you are on in four different search engines (including Technorati and Google)
• search for your highlighted terms in seven different verticals from local to TV to stocks.
