I disagree.

Signal does a very important part but not 90%.

what about news feed, events, calendar, status updates, groups, pages, profile walls...

These are all mega useful tools that are used by 2 billion people for a reason!

I <3 Signal and I've converted many non-techies to it but I cannot easily inform everyone that I'm having a baby and they also cannot do this.

But I'm glad you're using it. it's a wonderful tool.
