I think the risk is that designers focus on the "delight" of their design to the detriment of it's usability. Delight is important, but it can't cover the actual nuances of the user experience. This article gets into it a bit when talking about context. The original modal requires a context change by occluding the original tag. Focusing on the delight of the animation can blind you to this problem. The last example, where the context never full switches, but simply expands, is much better. The animation smooths out the expansion of the context, helping the user, instead of masking a problem.

Great page, really easy to see what's coming up and what's not. I wonder if it's backed by something like trello. The one thing that makes me sad is that retina support is again looking like it will probably be delayed.

I did something similar to this recently on http://touchstreamapp.com. In my case, I dynamically add animate.css classes, etc.

My problem is with your poor interpretation of what is donation to Prop 8 means. You have decided that it means he is bigoted and doesn't believe in equal rights. Just because you say so doesn't make it true. Sticking to your own narrow interpretation of a very complex subject gives you the freedom to make poor assertions that you parade as fact. Need I again point to our own president's swaying on the issue? It's not as simple of an issue as you believe it to be.

Again, you continue to put words in his mouth. He has never "so obviously and publicly" come out against equality. Support for Prop 8 comes from several different fronts, several of which are rooted in traditional governing stances on marriage, such as the role of population building and sustainability, etc, and not on a hatred for other people. I'm not saying their stance it right, I'm just saying that you, and others, have painted a very black and white picture when there are, in fact, several shades of gray. If you think otherwise, then I would suggest you go back and look at President Obama's remarks and evolving views on the subject.

You keep using the word bigot. Other than your interpretation of his donation to Prop 8, can you point to one single example of bigoted behavior? People supported Prop 8 for a variety of reasons, not just because they "hate the gays". Were some of the donors bigots? I don't doubt it. But, you are unfairly speaking for Brendan Eich when you interpret his donation as being nothing more than a bigoted action, without actually knowing his reasoning. In fact, he's been quite silent on the issue, even though his own company supports speaking out in public on such matters. The world is not as black and white as you see it. I understand that you feel strongly about this, but it seems like you are getting angry and deriding others on your own platform, which is sad, given that the instructions are "be nice, or else".

We currently use HipChat. We evaluated Slack, but it was too expensive for not much more.

Nothing is easy with flexbox. Between the three major changes in the spec, and every browser implementing the random parts from each spec they want, it's surprising that anybody can get anything accomplished with flexbox. That said, it is incredibly powerful, and will be great when everyone can get on the same page.

Great analogy of aspirational branding. It's really easy to get caught up in how every feature you make is soooo awesome. Start with people and their stories first, then show how your product helped them throw fireballs.
