Got my Freebase invitation yesterday, and logged in today. Yeah! A semantic web application, well done, clean and professional. AJAX is used and just works in Firefox and Konqueror (well, I tested again, right now; the WYSIWYG editor doesn’t work in Konqi:-(
There’s a lot of data to browse, and it’s presented well structured. Quite some data comes from the info-boxes in Wikipedia. This data is used to provide really nice autocompletion in your profile!
I’ve watched their introduction video… nice!
More to come…
