Videos are also a good way to promote your blog on forums and other websites.
I've seen people that don't necessarily vlog, but they post youtube videos of game trailers, song clips, etc.. on their blog. They would get more views if they posted it on their own channel with their intro in the front and their url in the description, its a great way to generate traffic!
If you want this video intro customized for you, just ask my friend Chris!
Here is his blog http://directorspace.blogspot.com/
Make sure you put the url of your blog in your comment.
Please only ask for one if you're going to use it, they are free though!
