I personally do not use it that much cuz my home page is set to Google, and each time I wanna search, I use google directly. I also use it for checking backlinks for pages. How often do you use it, or do you use it at all?
I only use it for visual PR and the occational backlink search. I use google website for searching same as you.
What do you mean? I use it to check the PR and it's always ON (Firefox here). So does that mean I use it all the time? I don't search via its search though.
