Hashtags are a community-driven convention (on Twitter) for adding additional context and metadata to your tweets. They’re like tags on Flickr, only added inline to your post. You create a hashtag simply by prefixing a word with a hash symbol: #hashtag.
Twemes lets you search for hashtags, grab a RSS feed for a given hashtag, and even embed the content of that feed in a blog.
So why is this really interesting?
I tested the Twemes widget about a month ago. I basically displayed a Twemes widget below a video, encouraging people to tweet the video with the hashtag #smartshopit, so that whatever their tweet was, it would appear next to the video, and the next person to watch the video could identify who previously saw it, and maybe interact with that person through Twitter.
Unfortunately, not all the tweeted hashtags appeared in the widget, but I thought that the idea had some merits.
What would you do with Twemes?
