Trying to find GIS information on the Internet can be like looking for the proverbial needle in the haystack. Well lucky for us we have a couple tools that enable us to see what other users are saying about topics we care about. I use my RSS aggregator to read the blogs that I feel keep me up to date the most, but what about the thousands that mention GIS?
Enter Technorati, PubSub and Feedster. These three tools allow me to use keywords or “tags” to find blog postings that match terms that I want to follow. What is ever better about them is you can subscribe to them with your RSS aggregator. I will use the keyword/tag “ESRI” to show you how each of them finds and displays blog entries.
PubSub is a little different than those two as you really need to create the keywords yourself, but I think I get better results with PubSub than Technorati or Feedster.
I’ve got PubSub feeds for ESRI, ArcGIS, PostGIS, Oracle, MapServer, Ka Map, Cartography and Geospatial. I don’t have one for GIS because you get many results for GIs (think Iraq). Any time almost anyone posts about the above terms on their blog, I get to read the post. I know many users know about these services, but if you don’t you should really check them out.
