I tried using it several times. But I am not satisfied with it. When selected, the "classic" interface is shown only to the owner of the account. I want my visitors to see the Vanilla interface :-)

See the screenshot, when a newcomer lands on my profile page they don't get to see any notice at all, they cannot scroll down either, because the sign-in box is automatically selected. They need an extra mouse click to scroll down.

Besides, the design reminds me of # and it doesn't work on certain browsers. And some people end up thinking this is just a Twitter clone. I would like my friends (who are new to !gnusocial ) to know the actual name of the project.
