Leo had been using Google Buzz to post updates to 18,000 people. For some reason, Buzz stopped publishing his updates. This is what he learned from that :

No one noticed.

Not even me.

It makes me feel like everything I've posted over the past four years on Twitter, Jaiku, Friendfeed, Plurk, Pownce, and, yes, Google Buzz, has been an immense waste of time. I was shouting into a vast echo chamber where no one could hear me because they were too busy shouting themselves. All this time I've been pumping content into the void like some chatterbox Onan. How humiliating. How demoralizing.
