| Examples of differentiation: - Signal end-to-end encryption - Discord game integration - Slack history keeping - Skype ability to make phone calls - Snapchat self destroying pictures You may not see any use in any of these but some people do. And some reasons why these aren't standardized: - it is hard to do without some form of centralization (ex: history keeping) - some services cost money (ex: phone calls) - some goals are contradictory (ex: end-to-end encryption and searchable histories) - owning a popular messaging network is simply too appealing |
