Last week You Tube announced that they will optionally show you search suggestions as you type. I really like this feature – it helps people formulate queries in an intuitive and familiar way. Most browsers have a similar functionality that will show previous queries you have entered – so people don’t have to learn anything new to use this.
My main complaint is that it is not on by default. You have to click on the advanced link beside the search box and select the option. So very few people will use it. I’ve also see some suggestions that don’t have any results – they need to make sure this doesn’t happen. However these are minor complaints. I’m sure this is a trend we will see more of.
