Very little time...
... and corresponding value in blog posts.
Worked a bit at an internet cafe this week. One guy showed up a couple of times with his laptop and all kinds of gear. He had a USB hub, fancy headphones, some kind of router or converter or modem or something slightly larger than a paperback book, a couple of other things.
With his mouse and power cord, it made a glorious complicated mess, and it all glowed -- you know, the kind of accessories that have blue or green lights that make them look cool.
I didn't see him spend much time actually *doing* anything -- he chatted with women around him, and talked about his equipment, etc. From the little I overheard I don't think he actually knew that much about technology. I decided he must just come in and set up all his stuff to impress the chicks. I hope that's working for him.
