Very cool @riking. Very excited about that!
I am also thinking about first time users who land on a topic page from a search engine or Facebook. We had over 4000 new users to the site yesterday, but only 11 registrations.
I think a simple flyout for these users would be helpful to welcome them. Perhaps I take them to a particular topic instead of directly to registration. Speaking of which, I’m not sure how I would link to. Some JS function I imagine.
I was just thinking I would add the code as part of the HTML header.
