I STARTED NOTICING issues with Foursquare earlier today, encountering 504 errors and the crying mayor at left. That's all to be expected when companies push out infrastructural changes. After a few hours of the crying princess, Foursquare returned to my handset with a new granularity. Specifically, I can now see every town and city in Ireland. There isn't much to be found in anywhere except Dublin, unless I'm in a town where other Foursquare users have manually input venues they have visited. In my social media module at Tipperary Institute, students will add venues with tips and tags in Clonmel and Cashel. We'll follow the lead of Keith Bohanna as he adds and tags things in Kilkenny.
