This question has been asked on the DO forum as well and I think it is not a good idea to list DO on that website. I think it will only attract greedy people who want to harvest as many free coins as they can so they can sell them asap. We need people that are excited in the coin and not greedy. Our community is growing nicely so no need to attract greedy people.
I agree with you. The main reason for me is that 16 weeks ago when our airdrop started, these airdrops were less common. DO then started an airdrop in the right way, involing the community and growing into something great. Since then loads have tried to imitate and airdrop in name, like ICO, has been tarnished by so much rubbish and scam accusations. While we're still mid-airdrop, we don't want to grouped with the rest of them, we're better than that.
We do need a way to get increased volume and sign-up, but I don't think that's the best way. Use of this forum, and other websites, can do that...I think we need a PR run, get some blogs and news outlets talking about Onion.
