Since March 2009, staff and students at Maynooth University's Department of Geography have written on a blog called 'Eye on the World'. You can access it via this link. Please visit, subscribe, search the archives, and comment on posts when they appear.
Another Maynooth blog some of us work on is called Ireland After Nama, which since November 2009 has intervened in the debate about Ireland's economic crisis and its aftermath.
Chris Brunsdon at the National Centre for Geocomputation publishes his work here.
Finally, our own Adrian Kavanagh runs a fantastic elections blog.
