One of the things I realized lately is the presence of dozens of communication tools, for instance WhatsApp, Twitter, Facebook Messenger, Telegram, IRC, Google Talk, Skype, SMS etc. Every platform has its own pros and cons.
My choice for these 3 platforms is simple:
- Facebook Messenger has great features and a wide contact list.
- Skype is the number one for voice communication
- Twitter is perfect for text-communication with people all over the world, but lacks the addressbook and user amount of Facebook
