Couple of useful websites for avid Foursquare users (like me).
1) Tidy Square: http://www.pinksy.co.uk/tidysquare/
Help clean up venues without addresses. Makes Foursquare a much cleaner experience and makes sure that venues end up being where they’re supposed to be.
Then when you’ve located addresses and pin locations you can submit the changes to:
2) The Get Satisfaction thread for Europe edits.
Easy to create an account for Get Satisfaction and submit changes for foursquare. I’ve been gently working on tidying up Birmingham and Telford. Together, comrades, we can make foursquare a better experience.
