Judy is THE person I have gone to for years for anything having to do with mobile learning. It's great to have her pull together content and bloggers into this community. In other words, Judy is marking good content she comes across as well as bringing in content from top bloggers in the space such as: Cell Phones in Learning, Golden Swamp, mLearning is Good, mLearning-World, mLearning: beyond the digital divide, mLearnopedia Blog, Mobile Commons, MobilED, MobileDot, moblearn, and uLearning Blog.
I've personally not subscribed to these individual blogs, but I've just subscribe to the feed from this site in order to have Judy continue to feed me good stuff. Thanks Judy!
By the way, if you ever have a chance to attend one of Judy's sessions where she shows examples of mobile learning - you should definitely go.
