We used to have this technology called email which seemed pretty cool. You could even embed photos of your cat.

Did they ever fix the spammer problem on it?

[dzhiurgis]

Yes.

It's not realtime, though. You send your message and the other person gets it... in a few minutes.

Did the implementation depend on one or more intermediate servers always being online? If so, it isn't revolutionary.

All our email clients do is send it to our email servers. Try sending email out of your own machine. I doubt 10% would reach the destination inbox. The general assumption today is you don't run your own mail server. :(
