Very slick and eye-friendly; kids would like to navigate this site. It has many wonderful features (though, if it's anything like DiscoveryEducation/ DiscoveryStreaming, it's low on my own content area - reading and writing). I think the fact that it's $9.95 a month would be off-putting to most parents, however.
I like the ideas presented here, but like Chris V. has stated, parents are probably not going to want to pay a fee.
This is very much like what we already have available to build our own web pages.Louise
