+1 To me it was more about saving mouse movements than hiding UI. Don't mouse all the way to the top of the screen to click that. Press this dynamic, context aware, button on your toolbar instead. If you'd still rather use hot keys, go for it!
When I was learning Flux I thought this video series[1] was really helpful. That being said, I've switched to Redux now and am much happier for it. If you're into videos I highly recommend Dan's (creator of Redux and on React core team) Egghead series[2].
A few thoughts on navigation:
I'm on a mac and I felt that the zoom using the "scroll wheel" (i.e. track pad) was pretty disorienting. I was expecting it to scroll. Having to click and hold down to scroll doesn't feel right.
I also instinctively thought the arrow keys would work but they didn't. I'd suggest up/down (obvious) and left = zoom out, right = zoom in.
It's not news but sometimes people get lost. It's really easy to get caught up in gold plating or chasing fringe customers. I think it's good to have a reminder every now and again. Focus on what your company is good at and win your target market. Adjacent markets will come if your target focus is executed at a high enough level.
This is a good way to show everyone that you have a limited amount of time and resources and that a company can't deliver everything in a reasonable amount of time. We do something similar with our product management process but instead of customers buying features we have internal stakeholders purchase them.
We'll take some percentage of a release and set feature "prices" based on a swag of effort. Then we allocate a percentage of release time as "dollars" to the stakeholders. We just keep track of it manually since it's all internal but we've found the process works nicely for feature prioritization.
I was thinking of making an app like this in the past. To take it a step further, I actually thought (still think) it would be cool to have a heat map of your entire life across the whole globe. Battery life issues aside, I decided to scrap the project for inevitable privacy concerns.
"Newer social news website such as Reddit Inc. also stole some of Digg's thunder. Last December, Reddit drew more visitors than Digg for the first time, according to comScore, and since then it has maintained that lead."
I agree - It's not that people aren't using Facebook mobile, it's that they can't monetize Facebook mobile. I'm not sure how buying Instagram fixes that.
It would be cool if you could change the start and end times. So instead of 00:00:00 and 23:59:59 I could do something like 09:00 - 16:59:59. Just another tool to get through the day!
If the average transaction is $500 and they move $350MM a year, that's only $175,000 in revenue. I know they are still a young startup but that's certainly a less sexy number than the headline tries to imply.
