It was very strange for me to see among my colleagues those who do not like to attend conferences and seminars. Over the past year I have talked with several of them, figuring out the reasons why people do not want to go to IT events. The main anti-motives for most:
Inconvenient time and venue.
Non-core or uninteresting topics of reports.
Laziness and lack of motivation.
If we exclude work schedule, then the main obstacle, in my opinion, is the last reason, which manifests itself in different ways. A small conversation very often helps to change the situation.
