Steamboat discussion via WhatsApp GroupChat

Whatsapp- Cool instant mobile messenger supported by almost all smartphones. But the uncool part is, not everyone is active on it. Few categories of users as below
The categories:

Type 1. Active and use it as a substitute for sms
Type 2. Installed it, turned it on only when neccesary
Type 3. Installed it, turned it on once and uninstalled it because it consumed too much phone credit

Study case 1:
Planning a steamboat via Whatsapp.

Intiator: Type A user, a new convert from normal sms, having the mindset everyone on the contact list is a Type 1 user.

Responses:

Type 1 user: Responded almost instantaneous, suggesting another communication channel to proceed with the plan
Initiator: Still firm that everyone is Type 1 user
Type 2 user: Responded after 6 hours
Type 3 user: Response not available until further notice

Special Responses:
Impatient Type 1 user: Left the conversation almost immediately after multiple messages.

Conclusion:
1. Whatsapp is still a one to one communication
2. Whatsapp spams like shit in GroupChat
3. Steamboat discussion via Whatsapp GroupChat failed

Hehehehehehe...
