Point Crawl Resources

On Sept 30th I posted the following on G+ OSR Community (Which I'm going to be deleting my profile shortly, so I figured I'd copy and paste these links so I have them for future reference). Link to discussion. 

Point crawl. Explain? How do you design one? Links perhaps? Is this a event based thing sorta?
