Why was it so good? For me, it was a combination of factors:
- A pretty unique mix of delegates, not the usual corporate conference crowd at all
- No big corporate presence, just open discussion (I wondered - unnecessarily as it turned out - if being an ESRI employee would actually upset people)
- Great presentations, especially Stuart Harrison's Easy Mapping demo, and Paul Canning's reworking of Jakob Nielsen's still-relevant Discount Usability ideas (well, 20 years after the original was published, only one person in the room had done any user testing of any sort!)
- The chance to get past the GIS departments and speak to the webmasters, PR people, and a whole slew of innovative minds - who are now busily filling the web with maps and spatial data, often without a GIS system in sight.
- Simple is good. By and large the public don't want really complex map data like OS MasterMap, they want pushpins on a Google map. MasterMap has a place though, for marking up planning applications for example.
- GIS Data needs to be indexable and mashable. Webmasters want embeddable maps and raw data: as KML or GeoRSS, not in a black-box, closed system that runs as a standalone web page. At one point the whole room was shouting "Raw data now!"
- Usability of old-school web maps, based on GIS systems, is poor. Usability analysis has been neglected for too long, but with just 5-7 users testing, you can find 80% of your site's defects.
