SoundCloud lets you very easily record an audio message — the first 120 minutes are free — and then you can post the link or embed it where you like. They’ve also just begun a new site called Take Questions, which TechCrunch calls a “Quora for audio.” There, you can set-up your own page to take audio questions that you can then answer — in audio.

I’m adding both to The Best Sites To Practice Speaking English.
