dev - developer
(developer on LTD).
Life events often necessitate removing yourself from the world just as you describe and I can easily imagine Ole (a real person, just like you and me with real life events) dropping out of the world/communication for a while and that this does not mean that he has given up on his projects.
"...and seeing that Ole has recently begun again to publicly reply to tweets"
is very good to hear and encouraging.about the future of Pythonista.
