Twitter publicly launched today seven years ago with a short blog post I wrote. I re-read that post and realized how difficult it is to even guess the future. What was mildly annoying, is something I can’t live without. It is a humbling reminder that as a chronicler of technology, I need to keep learning – as much as I can about everything and anything, all the time, and be prepared to be wrong – more often than being right. As a writer, the web is always there to remind me of what I got wrong .
