FOMO - Fear of Missing Out. A colleague told me that some news sites like the Wall Street Journal will let you see part of a story and then it fades out and you are given the option to read the rest by registering or logging in. For our current campaign, people can view posted ideas in their entirety but cannot comment on them or post new ideas without registration. I wonder if this method of allowing people to see a 'teaser' would entice greater registration. Has this been tried?
