I know several families through our inclusive homeschool group who use K12 or Connections. Many use it as a "spine" but still supplement with private or co-op classes, book clubs, etc. The majority are engaged in private music lessons, sports, book clubs, etc.
Soapbox alert
We have multiple opportunities to socialize every day. We have considerably more field trips than the students in public school. Sorry, but when someone starts talking about "socialization" it raises my hackles.
I will say this: Online school or homeschool--done correctly--requires an enormous amount of time and effort on a parent's part. They should call it car-schooling because you spend half your day in the car escorting your child to his various classes, clubs, and lessons. A website or boxed curriculum is not sufficient. Face time, a real science lab, making a mess that //I// don't have to clean up...it's all important.
I researched Connections Academy in August -- even went to an information night and considered enrolling DS11. In the end, it just didn't look rigorous enough for me. I get concerned when I look at the English curriculum and see that they only cover 1 novel in a semester, and the boy has already read them.
We are going to experiment with online learning later this winter with an AOPS math course. I'm looking forward to seeing how he likes it. I suspect it will be a big hit. He's already so wired in that he's practically a cyborg. He loves to chat, email, forum surf, listen to music, watch youtube, research homework help ------- all at the same time :P
