I really don't understand people whining and moaning about the lack of marketing from the development team.
Why not put all your energies into marketing Gulden yourselves?
As far as I understand it the dev team have stated that they code and develop the coin but don't market it.  That's the job of the community.
When it comes to advertising with a cost involved then that's different.
But it really costs nothing to publish an article, tweet it, put it on your FB page, write to online blogs etc.
If you're worried about your investment or the lack of recognition for an innovative and ahead of the field coin then get active.
If you're not part of the community then what are you doing hanging around in this thread?
