Show us / try it yourself! Take one of the bands (~125 Megabytes) and losslessly compress it as small as you can. Then share the results. Science is fun!
Also be aware that TIFF is super fast, which is important for some applications. And the scene compilation is already compressed with bzip2.
Any idea why temporal coverage is so spotty? According to http://landsat.usgs.gov/landsat8.php Landsat 8 repeats every 16 days, but for many of the spots there are only images that are several months old.
Opera Mobile (the "classic" one before they threw it all away) let you save pages for offline reading. Not perfect but better than nothing. Sadly it did not cache content through restarts which is annoying on mobile where apps get killed a lot. But if I recall correctly at least the navigation back and forward was instant, like on desktop, with no network traffic.
Your website is really bad for low screens. The static (WHY?!) header and footer take about 30% of mine. And there is no visual distinction between them and the content. Last but not least, the text is uncomfortably huge. I like to see more than 10 lines of text on my screen, I am neither a child nor sitting 10 feet away.
Krita is awesome. But, and I know this will sound weird to many people, I am now so familiar with GIMP's UI and workflow, that I find changing difficult.
As a user who sometimes has terrible coverage and 2G I would suggest not using AJAX so much. If you do, make sure it is cached by the browser. It is incredibly frustrating to have zero indication if there is some AJAX loading going on in the background or not. The browsers don't show and animated indicators that websites show, well, like to animate for eternity. And if loading stopped or you decide to reload the page in the hope that this time it will load better, sites usually fetch the whole shebang again.
So my recommendations: Make sure your site is split into nice, cachable chunks (css, images, js, etc). If you can, avoid JS. Avoid loading content invisibly to the user in the background.
Why not take the matter in your own hands, embrace your freedom and install some ad-blocking addon? Or use a tool like youtube-dl, mpv or VLC to simply watch Youtube (and other hosts) videos outside your browser.
I would like to archive your photo collection for safe keeping at archive.org in the winter. Would you be up to work together on that or should I just write me some scripts and go at it (with reasonable rate limiting)?
Are original files available or is thumb-2048.jpg the maximum public quality?
Are there really no location tags in the files? If so, your CC license is pretty much worthless as the images itself are not useful to anyone. :(
On the opposite, everyone should use it. I love using it for queries I feel embarassed about, like googling for illness symptoms or watching wildlife documentaries.
Emphasis on can. Of course it can, there is always outliers and there is nothing that can be done about that. However I would guess that in the majority of cases people beating do get handled. I am just guessing. Are you just guessing too or do you have some hard evidence or statistics to back your claim?
The problem is that people are different. Some people will like the diverse community at HN to scrutinise their work to potentially improve it. Otherwise just want positive reinforcement. You can't really put both sides into the same bucket and decide that everyone should sugarcoat all the time.
I love criticising and my projects being criticised as long as there clearly is knowledge or experience behind. What if you see someone making a huge mistake based on your knowledge, should you stay quiet? Making sure that feedback comes across as nice and well-intended can be hard and time consuming for people who speak English as a second or third language.
So maybe there should be a differentiation between "Proudly presenting" and "Looking for honest feedback" somehow?
