Only took me 31 minutes to get signed in to this so-called improved version of the site. First tells me my old login is no longer detected so I try to create a new one, then it tells me that that email is all ready registered which completely contradicts the original thing. So then I try to merge my google account which just decides not to work at all. At that point I just try a bunch of times to log in with my original login and eventually it decides to work but even then it took about two minutes and two refreshes before the page popped up with me logged in.
So yeah, very not impressed with the new site thus far.
