I think the advantage to my version is that there's much less of a barrier to making a skim.

1) You don't have to email anyone for an access code and subsequently create an account.

2) You don't have to wait to be emailed for link to your videos "digest creator".

I suspect that these barriers are enough to prevent most people from creating skims. See http://lesswrong.com/lw/f1/beware_trivial_inconveniences/ for the power of trivial inconveniences.
