Keep this thing going guys. I won't be using whatsapp myself, but for what it's worth, Nokia are not alone for killing Maemo/N900. There's been 100s of apps suggested in the Brainstorm section that have been dismissed by some community developers whith “What ya want that crap for? Go buy an Android”. Then elsewhere they complain about how crap Maemo is because there's no apps.
Where's the logic in that?
