I recently made my 300th video to put on my Valencia Property YouTube channel. There are actually 326 but some are private for specific clients or unlisted as they were only for friends or family. However 300 public videos is a lot.
The channel started in 2007 but not much happened in the first two years because there were bandwidth, equipment and time issues. It really took off a couple of years ago once I got myself a Mac which made making videos not only easier but actually enjoyable.
