Where to make useful contacts in IT?

Question

Contacts

• Conferences
  So far, I have found only Oleg Bunin's conferences for myself.
  
• Telegram chats
  Chat "Pain of the team leader" is more or less the norm, although there is too much Albert :-)
  
• Random coffee
  I'm just going to try it, I can't say anything about it yet.
  
• Something else?
