Did you see Brian Armstrong’s post on Twitter about adding a new listing on Coinbase?
I write a post on it also.

I hope it works. It looks like we are doing well but Digibyte is ahead of us in the polling. I hope we can mobilize some Steemian to post on Twitter.
Please do what you can.
Thanks!

Please tweet him that you think it should be Steem.

This is what I tweeted:
I suggest Steem, this blockchain has a social media application with one million plus accounts and various other decentralized gaming applications like Steem-monsters, Drug wars and also gambling applications like Magic Dice. These facts suggest that listing Steem is a win-win.‬
