Just spotted a proposal for a standard icon to represent geotagged content, the homepage is at geotagicons.com, can’t say a big fan of the icon itself, but the idea is great.
<OT>Was sort of involved in trying to find a standard icon for GeoRSS (in fact they use my icon as the favicon ), but not sure (in hindsight!) if that a good idea, really it just saying this is a geotagged feed, which really shouldn’t mean much different to the end user than the standard feed icon. If their feed reader is geoenabled – great, if not tough, although it can help people specifically looking for geo-content.</OT>
Anyway to try the waters, have enabled it for geotagged content on this blog, see the PhotoSpot category for example
