Other than the names being similar and possibly confusing the masses, I think it could be a good idea. Unfortunately, don't you think they would go for something other than Steem for payments. Perhaps IOTA?
I worry that since we are down in the 20's range for top cryptos, they wouldn't consider us. Unless they are looking at blocktivity.info and check out Steems transactions and see that Steem can handle the current load and A LOT more.
Do you think we could, as a community, get the witnesses together to try to write some sort of letter or proposal to Steam to get them to use Steem.
If this were possible, you would also see a massive growth of gamers utilizing the platform. Which could then be integrated into other things. Perhaps some way to use Steem with twitch.
The possibilities could be endless. I just think our biggest issue is being noticed.
