Then again, back on my N900 half awake brain once managed to pop a root shell, ps | grep, and kill -9 the alarm clock app without me having any memory of it (the shell was still open when I woke up naturally some time later or I'd never have known what happened).
Haha yeah, well. User account growth is indeed slowing and is down to 1% the last couple of weeks. I thought that was obvious from looking at the graph but I'll clarify it in the article. Recorded minutes are growingly steadily though and are still increasing with about 5% week over week.
