Dissemination vs Impact

A nice quote from ClipFlair project’s (http://clipflair.net) internal mailing list (the formatting is mine for your convenience):

…difference between Dissemination and Impact:

Impact is the measure of dissemintation.

For example:

– Organising a conference is dissemintation. 
– Number of people attending the conference is impact.

– Dissemination is how many e-mails you send. 
– Impact is how many replies you receive.
