I think that Steemit inc is concentrating more on developing the platform that no one has really paid attention to the front end as such. Most users today don't even use Steem to log in as they use another app like Steam peak or busy.org. There are so many now I have lost count.

I stick with the original but have looked at some of the others. Maybe in the future it will be bought up to date and given a face lift but chances are it wont.

I think the ppl behind Steemit were occupied with the whole blockchain and thus neglected the frontend. Steemit.com is not very inviting - but there are alternatives ;) Busy's been here for some time and now Steempeak is on the rise with motivated people behind it and a fast development of user requestes features.

I actually don't even use Steemit that much so I don't even notice. I have started using the esteem desktop app for most of my posting and it is pretty awesome.

The one thing I wish it had was a spell checker, but beyond that it is just clean and nice to use. You should really check it out.

My guess is the resources needed to update the interface are just not available. The team behind steem is working on other projects. Maybe with SMT's a witness or other group will pick up the reins.
