This thread has lots of interesting speculation & discussion; the maps bit was enlightening (for me, at least).

However, it's also full of the same old TMO blinkered/laser-focused wishing & ranting, i.e. "I want <obscure developer thing X> and <arcane technical thing Y>!"

If you look up from your keyboard and out at the regular phone-using public, you must surely realise how counter-productive it would be for Jolla to focus on these things at this stage to the exclusion of basic consumer functionality.

How about search in email app? How about contacts & calendar (yes this was mentioned here, but barely)?

Let them focus on that first. Openness is important, but for now our best hope is that Jolla provides support for the community to implement all these wonderful things. That's the best of both worlds: real people will actually want to use Sailfish, and the ultra-geeks can also use Sailfish on whatever hardware to do whatever grey-hat hacking things you want to do.

If Jolla can't appeal to the consumer, then they will sink without a trace and we'll be back to... what, exactly?

Exactly.
