Methods and systems for receiving feedback from a scalable number of participants of an on-line presentation. One method includes analyzing a screen change data set at a first computing device of an on-line presentation environment, tagging the screen change data set as requesting acknowledgement by the one or more viewers, and transmitting the screen change data set to the one or more viewers. The method also includes receiving a confirmation of receipt of the tagged screen change data set, generating a representation of the tagged screen change data set in response to receiving the confirmation of receipt, and displaying the generated representation at a presenter. |
