Hello Matthias,

Thanks for the reply and the lots of useful information in it.

Sorry, for sending my ideas to multiple forums.
My main excuse is that I do believe that the PMPC campaign can be a game changer and we should spread the message until it reaches everyone.

  
I have just contacted one of our designer if he could work on a PMPC
poster. Would be good if you could then spread those.

That sounds great. I'm looking forward to the PMPC poster.
(Please, don't forget to add the qr-code of string https://publiccode.eu/, most people understandably prefer scanning a qr-code over typing on mobile devices.)

 
Yes, I would love that. The question is: how do you motivate people to
do the same as you did? At the moment we mainly do so by the share links
on the website itself. If you have other ideas, please let us know.

That's a tough question. I don't know. I try to 'post' my enthusiasm about the PMPC campaign and hope that people will follow...

What do you think about trying to start a movement putting PMPC stickers to the doors of their flats and/or offices, taking a picture about it and sharing it on social media?

Idea behind the sticking: people crossing the doors will see the sticker and may engage in discussion about the campaign with the person sticking it.
Idea behind sharing: it maybe has a little chance that it become a social network movement and then the campaign may reach a lot of people.
A difficulty: only few people has stickers and it takes days to acquire them. 
Possible solution: before starting this "stick and post" movement sending a couple of (say 5 or 10) stickers to people who signed the campaign. (If this is not too costly)
Another difficulty: the possible initial posters are spread across plenty of different smaller social networks that are not necessarily see each-other already. The crucial movement-igniting-part of "leader", "first follower", "second follower", etc. may not appear concentrated enough to really start the movement. 

Here is a short but insightful TED video about starting movements: https://www.ted.com/talks/derek_sivers_how_to_start_a_movement/transcript

If you start this movement also in on diaspora* I would happily join it as first or second follower...

One particular action I would encourage you to do: spent the holiday
season to speak with friends and family about Public Money, Public Code
and encourage them, that if they agree, they should sign the Open Letter
https://publiccode.eu/#action

I use every opportunity to speak with people about the campaign. ;-)

I usually give them a sticker after or during the discussion for several reasons:
1. to help them remember the site where they can watch your amazing video and sign the open letter
2. to give them a little present that connects them a bit to the campaign emotionally
3. to increase the chance that the stickers go to some places where others will see.

Gergely, thanks for being part of the PMPC campaign!

My pleasure! I'm happy if I can help. The campaign is truly awesome!

Best,
Gergely
