Whoever made that first line chart should have used step interpolation. There is no point in time when none integer amounts of seconds have been added, but it gives the impression it's been smeared over the whole year
When I moved from the UK to USA it was the same in reverse. I had just got a new phone and number and immediately started getting spam calls and texts. I asked my colleagues how I could report or block these and they didn't really have an answer. OFCOM in the UK largely deals with spam and when I've had spam it's usually been that it comes from outside the UK but will still eventually get blocked
I used to write XHTML and found that if you server it with the mime type application/xhtml+xml then the browser will validate it, which can be a problem if you can't reliably output valid XML
The diagram showing the DSLR with the image the right way up as opposed to the eyes, is misleading as the camera is also captured upside down and then flipped in software.
For the size legend, the defaults are a bit odd. You should almost always be using d3.scale.sqrt() as you're comparing area, also zero in the domain should usually map to zero on the range.
I was given a Firefox OS phone at Mozfest last year. I lost my other phone earlier this year and so used it exclusively for four weeks. I'm sorry to say it's pretty terrible at this stage. I was using v2 of Firefox OS.
The problems are broadly that it was slow, unreliable and poorly designed. It would just become completely unresponsive a couple of times a week, requiring the battery to be removed to restart. There are very few well known apps. Twitter seems to be the only one, and it was so slow for scrolling that I gave up using it. The included apps were just placeholders to install apps, almost all of them only worked online. I wouldn't recommend getting one to anybody. I'm sure you could buy a cheap secondhand Android and have a better experience. It was worse than Android 1.6.
There's such a huge mountain of work for the Mozilla developers to get this to be in anyway competitive to Android. I think Mozilla would be better to concentrate their resources elsewhere.
I've been considering using CartoDB to replace Heroku. I only use basic geo stuff and their maps would be handy. The specs don't really tell you want you get for you money, there's a $29 which might be ok. http://cartodb.com/pricing/
