My blog service provider does not offer any functionality to embed a video in a blog post. It is only possible to insert a plain link to a video file. Does work as well of course, but is not as cool as an embeded video clip.
The solution was to join some video community, upload the video there and then embed that clip into a blog post as this one. So I followed the example of SP N scale modeler Denny Turani and joined Vimeo. So if you now look at the edited version of the previous post you can see the same video but now as an embeded clip. Nice, eh?
