Posterous better for podcasting than TypePad?

Uploading audio files to be embedded in posts on TypePad – and in the RSS/podcast feed which is managed by FeedBurner – appears to be excruciatingly slow.

I'm wondering if it would be more convenient to email the file onto Posterous, which will then post it on TypePad. I could then create a "multimedia/podcast feed" from Posterous, using FeedBurner, and offer that multimedia feed as a separate link on my TypePad blog.

Just a thought.
