I think it can depend a lot on the style you're going for, but also on what kind of video it is. With multiple speakers at once, I think removing a lot of silence can make it sound pretty unnatural. As a solo person speaking to a camera, or recording a screencast, when I'm not perfect out the gate (read: I repeat each line like 6 times), I've found it easiest to take a breath and leave a pause between each take. After that, the editing is pretty straightforward, just cutting out the silences and keeping the good takes. Some people are super comfortable on camera and can just talk for a few minutes and it's done... or memorize a script and knock it out... but sadly I'm not one of those people. Even with upfront planning, I'm more like "record 45 minutes to make a 5 minute screencast" so removing silence automatically is a huge time saver.
