Last week, I read the post from RubyKaigi's staff.

RubyKaigi has a tradition of using postcard-sized name tags. You write your name very big to your tag. Everyone can recognize each other.

Ok, Mom. This is my name tag!

And this tag shows some messages with a neat transition (inspired from Nakamura Yugo's work).

If you see a guy who wear this tag, please say "I read your blog." or hi or something!
