I've been thinking a lot about this lately. I attend at least 4 or 5 tech conferences a year and I always see teachers and edtech specialists running around with various gadgets (cameras, video cameras, webcams, microphones, tablets and *gasp* cell phones) creating content. But where does it all go? I've been searching for images and video from FETC 2012 and ICE 2012 recently and have been struggling to find anything. My guess is this footage is out there but that it has been improperly tagged. "Tagging" simply means giving the content keywords when it's uploaded. Those keywords become meta data that is searched when someone does search engine lookups. The easiest way is to include the conference Twitter hashtag such as #FETC2012 or #ICE12. This way one someone is searching for content related to the conference it will be easily findable.
If you are keeping these great memories to yourself and not sharing - I'm curious as to why? Get uploading and tagging! Share the excitement that enabled you to create the content in the first place!
