Yesterday evening, I received news that Allen Stern had passed away. For those of you not familiar with Allen, he was the founder of CenterNetworks and HTMLCenter, as well as CloudContacts and a handful of other informational and entrepreneurial sites. He was also the founder of Let’s Talk Fitness. I have probably known Allen longer than I’ve known any of my other online acquaintances (and longer than I’ve known a lot of people in real life). Allen was an amazingly friendly, nice guy with a sparkling wit.
