Twitter struggles with new features

The new Twitter features mentioned by Techcrunch seems to be live. However with some problems.

When I access the main Twitter site I get the user interface version that is tailored for mobile devices. Is it only me?

And the new Blocks navigation at http://explore.twitter.com looks nice. But is it really adding value to the navigation?

I found how to view a specific user in Blocks. I am at http://explore.twitter.com/blocks/#johan

Oh well. It's Friday. It's late. I'm going to bed. My guess is that the Twitter team will have stuff to work with :-) I will check back and see if it looks better tomorrow. I do like Twitter, but right now they need to improve the latest release.
