Indeed, Howcast is like a cross between (a text-oriented how-to encyclopedia) and . Just search for a topic of interest or browse by category, then click a video to start watching.

What distinguishes Howcast from similar sites (such as eHow, which also offers videos) is that it features professionally produced content. Most videos have a breezy, often comical style, and rely on actors rather than everyday Joes.

They also provide accompanying step-by-step instructions, a nice touch for those who like to read while they watch (and/or print out hardcopy for later reference).

Users can leave comments, suggest topics, and even author their own Wiki-style guides, which Howcast may elect to turn into new videos.

I particularly like Howcast's eponymous iPhone app [], which lets you watch videos anytime, anywhere. (And let's face it: Learning how to jump-start a car is easier when you're standing by your car, not sitting at your PC.)
