I visited the site. but they're way too aggressive over there to my liking. But I guess they are doing fine as a site, attracting lots of traffic
if you'll look at our statistics area51.stackexchange.com/proposals/1908/physics, we are definitely doing fine except for visits. they are far too low. we should do something about those google hits, I guess
unfortunatelly, I no longer have any idea about popular physics. perhaps I should look at some old Hawking books or something like that to get inspiration
as I said, I no longer keep an eye on popular science. at some point it stopped being useful. but I lost a contact with normal people interested in physics, which is a shame, I guess
yeah, mythbusters is definitely lot of fun. often it's more about chemistry and engineering though
the acceleration of the bike is relatively important, in the sense that the cable tying the bike to the tablecloth might be long and not under tension initially. so the bike can speed up first and pull the tablecloth later with a lot of acceleration
The guy who writes these posts actually just semi-recently moved his blog to Wired, but he's been analyzing Mythbusters episodes since long before that. So I don't think they necessarily have the writeups there because they're Google magnets. But I'm sure they get a lot of attention.
I'm sure there are aspects of the physics of Mythbusters that are unexplored in the blogosphere which we could host questions about
and/or we could go into more depth than some other analyses
