I thought that I’d post a few links to some of the QGIS and PostGIS pages that I refer to on a near daily basis.
GIS stackexchange – #PostGIS
This is a great place to find out the problems or issues that other PostGIS users are having. Sometimes though if the question is more Postgres specific then a post may be moved to the stackoverflow http://stackoverflow.com/questions/tagged/postgresql
GIS stackexchange – #QGIS
The main QGIS (http://www.qgis.org/) website encourages visitors to use the GIS stackexchange to ask questions. Quite often the questions asked are very simple, “How do i..” but to be honest these are sometime the most informative.
Perhaps not the most obvious place to look for QGIS or PostGIS information, but you can easily find people to network with and blogs/posts that you otherwise might not come across.
