What to do with my HD Video Camera....

So I have this nice Sony HD video camera that I want to start using for video interviews. In fact, my first video interview will be a week from Friday. I have already taken a number of videos with the camera and used the Sony software to convert the Sony AVCHD format to MPEG. Now I am wondering how to get that video posted to my blog simply and easy. I would like to retain it in HD format if possible but if shooting in 4x3 standard def makes more sense then I guess I can downgrade the video for now.

I have never really posted video to the web so....

What would you do?

Cheers!
