Hate to be _that guy_ but - this was absolutely unreadable on my wife's iPad - screen covering dialog, clicking only button "close" goes off-page to some wheel-of-fortune ad, and trying to go back from that floods the entire tab history with "Your iPad is infected with a virus" junk pages. Repeatedly on attempting to re-navigate.

Had the same on an iPhone. Just remembered Outline.com is for more than just dodging ad blockers, here's TFA[0]

Also, if you use Outline and submit an article it doesn't already have, there appears to be some kind of race-condition going on such that it stops showing the ad blocker but not the content. Resubmitting a second time usually fixes it.

How can outline be even legal? They basically steal the content of a website and create a new page on their own with it. It just happened that the content is stripped of ads for readability, but still.

Did you attempt to consume the article in Safari's Reader View, perchance?

I did not have difficulty with the site on an iPhone (though there could be locally attributable reasons for that), but I just checked and things look lovely in Reader View.

A few questions I got from reading this. Will a Fairy abandon its hatched chicks because of one imposter? Or will the cookoo have already pushed the unhatched eggs out of the nest?

The article said the imposter egg is deposited about 12 days after the Fairy wrens eggs are laid. For the mimic to push the eggs out, it has to hatch faster than the Fairy.

Google: Cookoos have incubation period of 9 to 14 days. Wrens 12–16 days.

However, cookoos incubate their eggs internally. So, by the cuckoo egg is laid, it has had 18 to 24 hours of internal incubation at 40oC and hatches 31 hours ahead of any host egg laid at the same time.

The said that Wrens abandon their nest 40% of the time. However, another article said Wrens only catch the imposter 40% of the time.
