Very easy to do. Video editing is so time consuming that unless you're a professional doing it for money, there's no reason to do it at all. I work in TV, and I know how much time video editing takes, even when an expert does it. He or she really doesn't. Perhaps someone can get a good video editing system and make one great production from a pile of home movies, but doing it over and over for the sole purpose of showing movies to your bored family and tolerant friends gets old fast.
Raw footage tends to be more fun and interesting than an over-produced amateur presentation.
I did a lot of video editing with a fairly professional Video Toaster rig a few years ago for some speeches I was doing. I got fairly good at it, but producing a minute of finished video still took an hour, not an uncommon ratio. Much of the time is spent looking through hours and hours of video to find what you need. The more video you accumulate, the worse this gets. Then there's the tweaking.
