Not Perfect but...

The for this see if you can use a dictation machine and Microsoft windows seven speech recognition to write a blog. 
This is basically a test to see if you can record what you want to say to an Olympus WS-110 Digital Voice Recorder then play it with Notepad open using Speech Recognition from Microsoft in Windows 7. I then copy&paste it into Blogger. The above is raw unedited so not bad.
