I would like to nominate @travelfeed, supporting the travel community on Steem for almost a year. We built up an almost 700 member strong discord server and are daily bringing great travel content forward (through curation) thanks to our tag #travelfeed, which would be otherwise lost if just tagged with #travel.
I'm one of the founding members and saw the potential Steem has for us travellers. The Travelfeed team consists also of @jpphotography, @guchtere, @mrprofessor and @saunter working all hard to make the dream of traveling while getting rewarded for your content come true.
We're currently developing a travel dApp and trying to make it the gateway to the Steem Blockchain for traveller who're not yet interested to dive into cryptocurrencies, yet.
