Is Beta really all its cracked up to be?

So last night I decided to switch my blog to this new Beta system, and it worked just fine--quite a quick transition actually. But now it appears as if comments can't be left. Is this true? 'Cause when I click on the comments button at the bottom of my post, it says that the blog can't be found. Is this happening for you guys if you try to comment? Just curious whether that's normal and whether it will change or not. Let me know if YOU know, and if you can let me know:) Email me if you have to!
