Friendly hellos, pleas for help, and antagonizing lolcat spam (you know who you are) are almost always welcome, and I try to respond in a timely fashion. Drop a line at jt (at) jtroll.com.
Click along to my LinkedIn profile if you want to get my professional contact info, or Twitter if you want to check ze tweets and drop a line in 140-character sound bytes. Chances are I have even more current work or other goodies I could share with you, should you be so inclined.
There are other methods of getting in touch, of course. Although semaphor is largely a lost art, I'm frequently within viewing distance of San Francisco's Twin Peaks, and a well-placed signaler perched on top of the hill there would have a good chance of catching my attention. If that doesn't sound convenient for you, just send an email! That's probably the safest bet, anyway.
