I talked to an EOS person on Telegram and got this reply...

As you said I also think they will have some big challenges ahead and needing to prove themselves to do something. I can also see that EOS attracts a lot of cool kids that wants to jump on the next Blockchain project... Steem is useable right now and have a big head start... If some EOS users are barely right now interested in Steem then why would they be interested in EOS social media? But I hope all succeeds since I think that will only be win-win for everyone.
