Hello!
1&2.) Hmm, I don't know Facebook at all. But I just saw
http://www.facebook.com/typolight ... It's public and has this shortcut... But perhaps somebody else knows how to improve this. It's just a bit better for people to tell them a "simple" name.

No, it's no stupid question about the wb.org, wb2.org, wb3.org. In short: wb.org is "outdated" as you can see perhaps in the whois - wb.org is kept by Ryan, but Ryan does not caring about WebsiteBaker anymore. The e.V. (association) is caring about websitebaker, and they have decided to use wb2.org. But websitebaker3.org - don't even think about it, it's outdated too because websitebaker3 was a thing four years ago...

As far as I know... Well, I don't know anything in fact about it, and I'm not the person to tell about this things...
Yours Michael
