Interesting story, though I think the title of this post could have been a lot more appropriate if he had stricken the word "how" and gone simply with "An investor who turned me down ended up sleeping on my couch." There's not much how here. Though I do agree, being kind and building karma is never a bad thing.
Right, the headline is misleading, at least to me. Sleeping on someone's couch usually means said sleeper is having a rough time and needs a roof over their head. I assumed this story was about an investor who turned Joel down, then hit a rough patch and ended up needing to sleep on Joel's couch out of the necessity of shelter. Still, a good story.
I can reassure you that having just returned from staying at the Intercontinental in Moscow with GOAP - I am not having a rough time.
