Here are 2 big reasons why I think Steemit is a failure,

1. The upvote system is broken and flawed with its architecture and design. As a result we see the same whales appear in trending everyday. @haejin clogs up half the feed with his posts. The articles that people find the most interesting never appear in the trending category because it's been hijacked by huge whales with voting bots (sybil attacks). Other huge whales who could potentially correct this never engage or curate. Somebody like @ned or @dan should be out everyday curating good content - but they never do. They are lazy and inactive users. All @dan ever does is withdraw money all day long, it's just a bank account for him. If he really cared about this platform he would hire people to use his account to curate content or police bad players.

2. Immutability isn't desirable. Censorship is needed just like an immune system is needed. People want censorship but they desire rational and fair censorship. People also want self censorship and an ability to delete old posts or fix spelling errors.

That's my feedback after a year here, thanks for listening. Good luck @berniesanders.
