I recently shared a short video with you that described social media. As you may know, the essence behind social media is sharing information - text, audio, video, photos, etc.
I just found an interesting application that allows me to share a stream of mentions of anything on Twitter with a background of Flickr photos. I've set it to stream mentions of "Sherlock" while backed with images tagged with Sherlockian. See what people are saying and what images show up:
This is also a good time to remind you: if you take photos at any Sherlockian events, please consider uploading them to Flickr and tagging them with "Sherlockian," to share them with other like-minded individuals. You might find that you'll connect with some interesting people that way.
