I will be curious to hear about your 7 year olds impression of the vidcast

Not sure how the younger ones will take to that.
LOL...it's a cartoon! What's not for the kids to love?
I don't know how much of a representative sample he's going to be...the kid is frankly brilliant. He reads nearly on a high school level, and he can tell you how to get to almost any major city in the US, complete with interstate numbers, junctions (and what cities they're in), and alternate routes, just off the top of his head. He's a little bit scary, actually, and figuring out where to direct all that grey matter of his is fairly daunting. Point being...while he does have a lot of interests in common with other 7-year olds, he also has many that are just not even on the average 2nd grader's radar.
Ok, so now that I've given you that disclaimer about my particular child and his potentially skewed feedback, I will tell you this: I let him watch it this morning after he was done getting ready for school, and he loved it. He kept looking for himself in all the ride-a-thon footage, and was upset when we had to cut it short so that I could take the laptop with me to work. Big thumbs up from both of us on the video...I love the set, and was cracking up when you came out and waved at the beginning, with all the clapping. Absolutely classic!
Please don't make the audio podcasts go away, though. Although I love the vidcast, I really like the frequency and regularity of the traditional weekly podcast.
On a bit of a tangent, he also liked the Freezing Host Lily's Room story...he hasn't heard the audio podcast yet, but I told it to him to illustrate the fact that even adults - and even COOL adults - mess up sometimes. On top of being crazy smart, he has trouble with perfectionism, and puts a lot of pressure on himself. It got through to him and made him smile, so know that your faux pas did do a little bit of good.
He's going to be with his dad this weekend, but after he gets home I'll have him send you an e-mail so you can get his firsthand impressions. He'll be absolutely thrilled that you want his opinion!
Sorry so long. I do tend to get wordy when I'm talking about my boy.
