It's worth noting that YouTube is optimising for the opposite: they want to prevent artificial view count inflation. Therefore, this behaviour (the view count not increasing when the videos are automatically accessed) would make sense.
If you're interested, an interesting measure for difficulty is how much companies charge to "buy youtube views" (e.g, $16 per 1000 views is ~8x the cost you'd pay for typical CAPTCHA solving).
Looks slick! I've used Google Calendar to achieve something similar in the past but this looks better.
Minor suggestion would be to remove the unlimited text messages from the plans. It's harder to change later when this takes off, is ripe for abuse, and (to me) makes it feel unsustainable: everyone know unlimited is not actually unlimited. I'd reserve that for for the "call us" enterprise pricing options.
There's one airline in particular that I dislike simply due multiple bad experiences. I vocalise this significantly. I still book their flights if it's the cheapest: I'd argue to myself that (a) flying is a transient experience and (b) I'll use the saving for a 'free' lounge pass, taxi to the airport, etc.
I wouldn't assume that just because people vocalise brand loyalty, means that they stick with it when it's time to open their wallets.
Shrug. I hear time and again people say they make it a point to always use Lyft, even if Uber is cheaper. So it's certainly not a 100% sure thing that people will always pick the cheapest option.
Landed in Sydney a few weeks ago. First visit so I ordered an Uber (as I've used it a lot, trust it, etc.).
After we were picked up, the driver helpfully informed us if we'd ordered the same ride via Ola (he drives both), it'd have been ~50% cheaper (as a new user).
Naturally, I installed it and now I'll switch between Uber and m Ola. This then expands to Bolt, Grab, and so on, and you realise it's virtually the same experience with different branding and the sole differentiating factor is price.
I definitely buy the convenience aspect: it's way more comfortable to pull out your phone and order a ride on a platform you're already familiar with. My trouble is the barrier is so low to install another app (and new joiner incentives are financially motivating) that this leads to virtually no brand loyalty.
Perhaps in a different world, where there are no up significant upfront financial incentives and perhaps drivers were exclusive to a platform (i.e. to pass their rigorous screening processes is a sign of quality), that'd certainly buy some loyalty from me.
Not OP, but in the same boat, and currently travel regularly. I always almost all of them installed (e.g. Uber/Lyft/Ola/Bolt/Grab etc.) and pick the cheapest. For now, there's the added incentive that you never pay full-fare for your first ride, too, so new competition is great.
Thank you so much for your incredible public service. I wish I could offer more than words. Lots of organisations discuss their values, but when push comes to shove, I don't believe many would even consider, let alone commit resources to, something that has such positive externalities.
I regularly see your comment (or ones for similar services) on these types of posts.
I assume the strategy is working as you keep replying, but have you considered starting posting yourself, as a measure of "you can independently verify how quickly we spotted this outage"?
(For what it's worth, for the alert component you can do it yourself for free by subscribing to individual status pages (assuming they have the option) to the email-to-Slack integration.)
