I haven't been posting much lately, as I've been looking at / listening to a lot of podcasts, trying to figure out how useful they might be to English language learners, and even if it's worth trying to get learners themselves involved.
I've been doing that on my Yahoo360's blog. And relating to this new tool from Yahoo, I'm not convinced yet...
There are things I do like about it (see the blog for more details), but there are more things I don't like about it. At least, I don't think I'd use it with students.
Check out my Yahoo360 blog for more on this, and on podcasting.
