As I attempt to archive some G+ communities for posterity into some static Jekyll sites, I ran into: Liquid Exception: Invalid scheme format: external links for which there were no search results. I’m not used to error messages with no search results. it made me feel special.

It turns out that Liquid assumes that a : character in a post category must be part of a URL, and replacing the : with : resolved the problem. Took a while to track that down. ☺
