Anyone who sees your content on any of these platforms can vote, comment, follow you, and do most of the things that Steem blockchain provides.

The different platforms are made with different purposes. For example, Busy.org provides a really nice interface, 1Ramp is for creators, communities, and contests, eSteem is a mobile front-end for steem. And Steemit is the first platform that was built on Steem.

Those are not different accounts. It is like accessing Steem blockchain from different apps. To access those platforms, you can log in using the same username and password (SteemConnect or posting keys) as you use on Steemit.

A lot of people find it hard to earn on Steemit. But building a reputation on Steemit and a vote value is a process. People who are steadily earning on Steem has spent almost a year by posting regularly, interacting with others, participating in contests/challenges, and establishing an identity.

The circular voting, vote blocks, groups, bots etc. are big flaws with the Steem model. But the community believes that different platforms and the Steem inc. itself is trying to fix those things.

Also Hive account@reveurgam, the kind of reward model that Steem has built is one of its kind and it'll take it years before it becomes perfect.
If you've any suggestions on improving the Steem ecosystem or any platform, I suggest that you write about it on your blog and tag the official steem accounts and the developers associated with the project. I am sure they'll reach out to you. I'd also like to know your suggestions on how we can make Steem better for all.

Thanks.
