Search box

How many people realised that there's a search function at the top of the page? I ask because I didn't realise at first and was looking into how to make a search box and even put it into the site before I finally noticed the built-in one. If people don't generally notice the little search bar at the top of the window, I'll put a more visible search box in. Please say whether you did or didn't notice it in the quick poll at the top of the page (I realise you may have already done that before reading this.)
