Absolutely, in terms of number of users and accounts, it hard to beat a platform that starts out in a super power country with >2 Billion population and utter mania when it comes to latest apps, startup, and investment (or anything todo with multiplying capital).
In terms of content, and diversity especially in the English language, it will take ONO > 1 year to catch-up and overtake Steemit as the goto location for not just latest crypto information but also general web content.
ONO is at a disadvantage here not because of Steem's 1st mover alone, but because it has not place an emphasis (yet) on sponsoring communities that foster growth and retention of talent like Stem, Curie, ComedyOpenMic, or even delegation to DAPs like Steem has, but this can change quickly if leadership in ONO deems it necessarily so.
ONO's primary team is more familiar with user acquisition (that Team has already proven they can ramp up to 1 million users in just a few months in their prior location based social media experimental project called ERA) but ONO is less familiar with community building as compared to Steem. Most of the Steem communities are build by leaders on Steemit using Steem.chat and Discord. To replicate this, ONO has to recruit and retain at least 100s of such caliber leaders to play catchup.
You haven't even touched the topic of platform stability at all. Who would want to use a buggy platform?
were you around in the 1st week of Steemit or first month or 1st quarter, as a coder, software architect and current pm, as long as it's improving it's normal, ONO is probably doing it Chinese dev style....rapidly improving. Their user base will grow in the tens of thousands just like Steem does even with all the 101 bugs.
oh yeah they are asking for early beta testers to join to report bugs and stuff, this is not their official launch.
if it's any help - if you get the ERROR mesg, it's their server end, shutdown the App and try again (I did it like 9 times yesterday before I enrolled successfully with International code, don't use their local beta test code you only get 100 ONOT, international testers get 500). If you get Code Error, use VPN to a different location (free www.tunnelbear.com) should work.
