This is a weird critique of R-Squared. You (should) learn very early on that comparing R-Squared values of different models is a no-no.


And you're claiming it's weird because people learn this early on? Maybe that's where we disagree -- it's not as common to learn about the issues with R^2 as you might think.


Maybe the fact that this is in the (reasonably brief) Wikipedia entry on R2 is some evidence?

https://en.wikipedia.org/wiki/Coefficient_of_determination#I...

Also, I find that the OP is actually more confusing on this topic than Wikipedia.

Not sure how else I can support that this is a basic fact about this metric. I'm not in the mood to find quotes in intro textbooks, etc.


Yeah, absurd that people are glossing over the fact that he outed (with photos for chrissakes) a rape victim.


She asked him to take photos (unless he's lying). While not stated, there's a good chance he asked her if he could post them online.


> and asked me to take lots of pictures of her for my memory

For his memory. Clearly it wasn't a "tell my story!" Kind of moment. Even if it was, she'd been raped the day before then tried to flee the country with no money, got arrested and thrown in prison. She was clearly in a very vulnerable state and the writer was the first friendly face she'd seen. He admits he didn't contact her before posting her face all over the internet. The pictures have been taken down now btw.

Edit: OP says she asked him to tell her story. I still think he should have asked her at a time when, you know, she wasn't at the lowest point in her life.


Companies frequently defend themselves against shareholder lawsuits, and naturally that money would otherwise provide value for the shareholders. Also, if the SEC fines them the (current) investors will basically be punished!


Oh fascinating, I hadn't thought about this before. So if the plaintiffs win a shareholder lawsuit, they're winning money at the expense of all of the other shareholders? And what about a class-action by all of the shareholders (is that even possible)? That'd just be the shareholders suing themselves? I guess that'd just be a forced liquidation/dividend in effect, right?


That's exactly what a bubble would say in this situation.


Damn you got me


Is this a press release?


Any bio-availability studies on that? I assumed the high doses were because uptake was bad / it was destroyed by stomach acid.


The whole "bioidentical hormones" thing some describe as unscientific, but I've been taking 10mg synthetic without knowing I've overdosing (that was the most popular OTC dose) with no effect. 0.3mg Herbatonin works pretty quickly. Here's something I just found: http://www.naturalhi.com/media/custom/Newsletter%20Melatonin...


Sounds to me more like a justification for presenting useless statistics and allowing 'outpacers' to give themselves more confirmation bias (which those communities already provide in spades).


Except even this doesn't make sense. Presumably Vine handles the videos on its own backend, and you only get your social graph when you move over to Instagram.

Unless you're going to provide free infrastructure for every component (not just the social graph) there will be an element of lock-in to virtually any social product.


App.net's API does providing more than a microblogging API. They have a file hosting (each user has their own quota), permissive messaging (point to point or group), and a search API so you can easily find anything on their system. They're planning to add more useful APIs, such as billing.


Seems like bad business strategy to build on top of those if it means it's easy to steal away your userbase. Sounds fine for mid-size apps who can't justify rolling their own though.


If your only competitive advantage is user lock-in, then you already have a problem. Either you need to get your userbase to grow big extremely fast, or you've already lost.


And if you grow the user-base fast you've won, right? Lock-in and network effects matter enormously. Saying you can't lock-in the social graph neither guarantees a company won't lock-in elsewhere nor guarantees this is an appealing platform on which to develop.

This isn't a morality tale, I'm just pointing out what kind of decisions would be made around App.net and that the Vine/Instagram example doesn't really make sense.
