Cloud Mapping Compared

So after coming back from the NACIS conference I've been looking at cloud mapping again.  At the conference Mapbox, CartoDB and Leaflet and ArcGIS online were getting a lot of mentions.  Compare that to searches from Google trends:


My interpretation is that:

• The non-experts are using/interested in ArcGIS online or Google Maps Engine
• The experts are interested in the others.
• Cloud mapping is on the up (as far as search terms go anyhow)
