GRASS,GVSIG,QGIS confused?

• GRASS has grown in terms of # of developers until 2008 this growth has since then stabilized
• gvSIG had a peak between 2006 and 2008, during which they seemed to have become the desktop GIS software open spurce reference, but its growth was reduced in both terms, contributions in releases in terms of No. of developers involved
• QGIS has had strong growth both in terms of contributions in the releases of both in terms of # of developers between 2004 and 2008 with a trend of steady growth that has taken every 4 years to double the # of developers involved so maybe today is the good tool among open gis desktop reference sources
