InsideGoogle points out that video upload is now a feature of Blogger.com, owned by Google:
"Videos do not count against your limited free storage space for images. They are automatically added as enclosures in posts, so every blog using them is also a video podcaster and compatible with most podcatchers. In other words, people can subscribe to your blog in software like iTunes and automatically download the latest video."
I would be happy to see my favorite medical/science bloggers start producing videocasts by using this simple (and free) method.
This Google video shows that it takes about 2 minutes to start a blog on Blogger.com. Creating a web site has never been easier.
