I met Mika Raento at the PLAN workshop and I loved his application ContextFlickr immediately – it finds information near your phone – like bluetooth device ids, cellids and GPS coordinates if you have a bluetooth GPS like me (since yesterday 🙂 and uploads them with your picture to flickr, as tags. So you get a lot of cool ways of grouping your photos, automatic GPS tags for use with geobloggers, georss and WorldKit etc.
Anyway, he’s got a shiny new version called “Merkitys-Meaning”. It works lovely. And (like Shozu) saves you money if you’re an inveterate moblogger like me and were previously using MMS. It’s GPLed. It’s ace. Try it!
p.s. tripletags!
