Whether or not I would be taking on liability by providing the service has been discussed, yes. I'm not exactly sure where the conversation will end though.
Yes, adding the ability to Check-In using an SMS number is on my wish list too. The SMS provider I am currently playing with allows this but not looked into it seriously yet.
Thanks for the feedback. I never made any point regarding type-safety so I'm just going to gloss over that. I have no issues with static typing.
Also, I did not mean to say that you should not move to something that inherently runs faster, that would be perverse. However if I have a system written in a language that already works I would probably start by looking at algorithms and architecture before pulling the New Language card.
Once you have a set of interoperating services then re-evaluate which, if any, individual services are my performance bottlenecks that could benefit from the effort of re-implementation in a new language.
The really interesting discussion of course would be one that included engineers from Twitter and their recall about what happened.
I have been in enough design meetings to know that their strategy didn't emerge fully formed from the mouth of one person.
No idea why you think I would rather not use my email client that is configured correctly, doesn't require I state my email address, possibly has sig file and ensure that only people with the latest and greatest browsers can contact the business that implements this.
People have been griping about crappy contact forms with no option to use real email forever, this is so retrograde.
Can you elaborate on the institution to which you belong, either here or over email? Would like to discuss further.
