Best speakers and lectures

Notice: The best speakers and best lectures are selected according to the following criteria:

• The number of visitors must be greater than the average number of visitors on all lectures
• The average rating must be higher than the average rating on all lectures

In the case of a lecture with more than one speaker, that lecture may be included in the list of the best lectures, but those speakers are omitted from the list of the best speakers because we did not evaluate them in such lectures individually.
