Because the charismatic ones you are less likely to notice. Also most people who work for Evil Corp know their company is evil, so if a polite charismatic person is taking advantage of the system you’re less likely to go dig out what they’re doing.

For example if in OPs story the guy had been polite and charming, he would have never gone into his account to check what was up, because it would be just a nice customer being nice. What’s to tell you that there weren’t other dozen like that that flew right under OPs nose, just because they never awoke suspicion.

Have you watched Primer?

But that is internally coherent from what I remember. I.e. time always works that way, changes in the past are propagated, and time travelers get the effects sometime after it.

The biggest one for me is in Butterfly effect, when he goes back in time and gives himself the scars, it goes against everything we learned about time travel in that movie. If he did that he would have had the scars all along, they would not have appeared out of thin air, also the timeline would have diverged there.

Oh yeah, because everyone will obviously remember what a guy mentioned off hand on a random episode 5 years ago.

I agree that a “previously on” for what happened the previous episode is bullshit, but that’s almost never the case.

Season 3 is out, just not all of it yet.

I see lots of excellent responses, but one of my favorite games is never mentioned, so I’ll mention it here, it’s Out of Space it’s essentially overcooked but calmer.

Someone else already suggested it, but I would second Terry Pratchett. Even though most of the books are standalone, I recommend start with the Colour of Magic and follow publication order.

I’m a backend server programmer, and although I have never worked on reddit I can imagine the conversation a few years back:

Dev A: How do we implement private? Should each post have a private flag or do we join on the subreddit to get it?

Dev B: that join might be heavy for the front page since we might have several different subreddits, a flag in each post is faster.

Dev A: But that means that whenever a subreddit goes private we need to flag all of the posts there

Dev B: yeah, but that doesn’t happen often, the front page gets accessed millions of times, most subreddits never change status, especially larger ones.

Dev A: I guess you’re right, even a large subreddit will be done in minutes, what are the odds of several large subreddits going private at the same time?
