Hello. I'm Kake. Please tell me if I do anything wrong.
I'm one of the people who wrote OpenGuides. The guide I contribute to is the Randomness Guide to London — if I get the hang of this GPS thing I'd quite like to convert all the RGL location data to GPS-gathered coordinates (as opposed to “I went and clicked on a map and looked at the URL” ones). This may take a while, since it currently has 715 nodes with location data.
