Usually when meeting old timer GIS users in academia or government, there are a bunch of questions I get asked about how OSM data fits into the more traditional GIS model where data is organised into shapefiles and layers.

Since I could not really find a simple article which explained the difference, spent a few minutes today to come up with a (possibly) easy to understand benefits table for someone in Government. Its not technically accurate, but could quickly help pitch the idea for opening up more data.

Its still very rough, feel free to contribute any suggestions/improvements that could make this useful.
