If you want to learn and improve as a developer a good entry point is to join a Maemo 5 community project you like and offer your help porting it to MeeGo or MeeGo-Harmattan. This might help you finding more bugs and rough edges in the underlying platforms, which is very good feedback for platform and application developers at this point. Also important: enjoy the Summer!
