I don't entirely agree. At this stage Jolla is only interesting to tinkerers, hobbyst-developers and Finns, still morning for Nokia demise.

Of course, in the longer term, Jolla wants to attract regular users, but the "ecosystem" is too small at the moment, or, put it another way, many applications that regular users want are out of reach. So, listening to developers/tinkerers (their current customers) is important. Also, developers are people too, and they too need many things regular people need to make use of their phone. So in the end it is all a question of balance.

Also, consumer-level features cost money (Maps, social networks require licensing/partnership), while improving the lower levels requires the time of already hired engineers...

And with the right infrastructure in place, "consumer" level feature may be developed by third parties and tinkerers.

So given there is a finite amount of money and time available to Jolla, they will have to invest them wisely... And I think infrastructure will need to be a big part of the improvements to do from now on.
