Spanish blog for my students.

All you have to do is to write an email as your post (as I am doing now) and send it to Posterous. Posterous takes care of the rest. If you want to send a video, you attach it to the email or copy the URL into your email and Posterous will show the video in your post. If you want to send a picture, just copy the image location or attach it to your email. Again Posterous will show the picture in your post. If you want to send a slideshow or a document, attach it to your email, Posterous takes care of the rest.
I did a lot a recordings this year with students using a little microphone plugged into my laptop and Audacity. I save the recordings as .mp3 files and attach them to the emails I send to Posterous. Posterous insert the audio files into the new posts and this way, students can listen to their own recordings (which they looove!).
So far so good... They are not many comments made by students yet, but I know it takes a while and it is a learning process. The blog is http://spanishblog.posterous.com/ and of course, your comments are welcome as well :)
What about you? which platform do you use to blog and why?
