Not quite the same situation, but I had a similar experience.
I was sitting in my office at work and a fellow employee (same company, but we don’t work directly with each other) that sits two offices down from me stopped by to chat about something work related. I can’t recall exactly how the conversation came up, but we began discussing his home being in escrow (he was the seller).
After a few minutes of explaining that I had done the same last summer and my thoughts on the current housing situation, he asked me if I had ever heard of piggington.com. Ironically, I had it minimized on my desktop, as I had just posted a topic, so I maximized it and said, “of course!”, and that it was one of the key factors in my decision to sell!
Before this conversation, we had probably only interacted a few times, and now we chat at least once or twice a week about housing, heh. I respect the desire to remain anonymous, so I’ll let him fess-up to being my co-worker if he reads this thread 🙂
