Le's just hope Universal and Apple make nice sooner rather than later, because the absence of a major label from iTunes certainly isn't gonna do anything to turn us into a nation of taggers.
Pentax's Optio WG-1 GPS point-and-shoot satisfied geotaggers out of the box, but owners of its K-5, K-r and 645D DSLRs have had to make do with third-party taggers like the PhotoTrackr or Eye-Fi.
Some taggers knit small cards into their work with a name or website for onlookers to get more information about the artist, but others do the work anonymously, often in the evening or early morning to avoid detection.
