Avi appears to work at cincom which I've just learned is where ParcPlace-Digitalk Smalltalk ended up. I imagine him (based on 10 minutes surfing his blog; I'm feeling reckless today) to be a wistful Smalltalk guru...
I liked Dave's post, but I'd like to clear up a couple of misconceptions. First of all, I don't work for Cincom, they just generously host my blog. But second, I don't think I could be described as a "wistful Smalltalk guru" - I first started using Smalltalk less than four years ago, having worked with most of the more "modern" development environments and found them lacking. In an inversion of the usual pattern, Java, Objective-C, and Ruby are in the past of my development career; Smalltalk is my present and, I suspect, my future for a while to come.
