It was inevitable: Bloggers who previously wrote endlessly about everything from politics to tech tips to how to fry an egg on a hot sidewalk can now take their commentary, advice and random experiments to the next level by filming and broadcasting their work, thanks to the latest web trend — video blogging.
Video blogs — also known by their shorter, clunkier name, vlogs — are blogs that primarily feature video shorts instead of text.
