Well it is important to remember that steemit is just a front end website that views the data on the blockchain. Steemit Inc. refers to the steemit.com website as a concentrator. There are other concentrators and anyone can make one. So saying steemit.com is in beta doesn't mean they consider the steem blockchain beta. In addition, technically any company that is always adding new things could leave the BETA stamp on their product indefinitely.

I do think any company should respond to feedback and attempt to adjust based upon that feedback.
