Here’s a short story of my attempt to make a small contribution. There’s a decent and maintained native browser for Aurora OS. I requested the developer to make it available for Sailfish X; my request was ignored. I suggested that Jolla could make such a request as a corporate entity (which gives it more weight), bot no one seems to care. I’d expect the same attitude from all other developers for Aurora, although there’s a number of useful apps (including Office) which could be shared with private customers. Neh, I’ve had enough of me of knocking in the closed doors.
As for ‘spreading the word’, many of my friends make fun of me when they see me struggling with my phone, when I’m trying to do some basic tasks: opening a webpage in a browser, ordering a taxi, trying to use navigation, this always “sorry, my whatsapp hang after I finished the call”. They’d see my advocating a switch to Sailfish as rather ridiculous and pathetic, because the user experience they see is a perfect anti-ad.
If you’re a blogger you can dedicate a part of your blog to spread information that Sailfish option exists. If 10 users can bring another new user, I’d consider it already a good achievement. Jolla support team would hate you for bringing another pack of newbies though, I guess.
