Brainboard.
Your message will be left on a custom "sticky".
Relevant adverts will be interpersed, on a dark background.
Your note will contain your: name, profession, title and idea.
You can mix up the ideas on the brainboard to create new ones.
You can build up a team that way, and mix and match ideas...
As the brainboard gets really full, it could be interesting
to correlate the data...
