I was asked why I decided to get a blog after being opposed to it for such a long time (even though my research at school is all about mass collaboration and ubiquitous computing - yeah, I know an enigma wrapped up in a riddle).

The simple answer is that I found myself posting comments on other blogs and wanted to leave a trail of breadcrumbs.  A comment by itself is not sufficient to reveal motivation (or lack thereof).  But being able to see some of my other thoughts should help the reader realize if I have something useful to add to the discourse or to the noise.
