That’s the title of this post on SkypeJournal and I have to admit I was a little confused at first, but reading the post cleared things up:
What's a Skype to blog call? Well don't you want your blog to capture voice comments from readers? I certainly do.
So how do you get it to work? Essentially you have the Comment link force an interaction with the Skype API and divert the call to a program called Pamela, which records the call and returns a URL that links through to recording.
Sounds a little complicated and definitely sounds like it won’t work unless your blog lives on a server you control, but the concept is really interesting.
