Same. One thing that I've noticed is that this seems to be a rebellion of power users and not the average Joe, which is why this has gotten so much traction on HN. To the Average Joe, if Apollo shuts down, they'll just download the Reddit app. However, HN users look at the Apollo dev and see themselves, so they're jumping on this out of solidarity.
I personally think this will last a few days and then all the default subs will either open by mod decisions or be forced open by Reddit admins. If it's the latter, I expect all existing mods to get the boot and replaced with people who are friendlier with Reddit admins. I also expect that usage of the official app will jump and there won't be any major disruptions to Reddit usage.
