BB #61: News Bubbles

I have a growing list of links to articles that catch my eye, things I’d like to post about (for whatever reason). But there’s a tension between posts based on lists of links or draft posts or idea files versus posts based on what I’m currently thinking about.

I seem to feel the latter isn’t enough, that I need a reserve for “lean times” — which never happen. More and more, I post when something strikes me as worth the effort. The “idea pile” seems almost like homework.

At work, more than a decade ago, Wi-Fi let us take our laptops to meetings or the cafeteria or even nearby outside. At home, while the old laptop couldn’t hold a connection, so remained tethered to the DSL modem, the new laptop does just fine. So does the iPad, going on two years now.

The new laptop uses a wireless keyboard and mouse. And I’ve been using wireless headphones to watch TV for a year or so. It’s really nice having no wires for devices I’ve used for so long in tethered form. Of course cell phones started it quite a few years ago.

It all does seem to come with a new set of (minor) headaches, though!
