I think it has more to do with drawing the homeschoolers back into the tracking and reporting systems and keeping them bored and busy. I'm not a big fan of online schooling. I think real life is far better. When my kids were homeschooled, their 'online learning' came from muds, FARK, chat, ripping music and finding lyrics etc. to get up to speed on technique and method; they learned the basic skills in order to be able to do and play and be che cool knowing all the lyrics to all their favorite songs and such. So whenever they wanted or needed to know something else it was just the most natural thing for them to look it up on the net.
While I really, really dislike the particular social skills and customs the schools teach, it was very difficult to find anybody near their own ages to hang out with who was not either locked up in school or had any clue what to do with themselves w/o a teacher, a bell or a clique leader to tell them what to do when they weren't.
