A couple of weeks ago Kim Woodbridge wrote a very interesting post on environmentalists who use Twitter. She even built an opml file of all the blogs associated with those tweeters - a very useful resource for those who follow people who discuss sustainability issues online.
I found it interesting, then, that Ms. Woodbridge decided to make an opml file for the blogs, but she didn't do anything with the twitter feeds. After all, many folks use twitter for somewhat different discussions than they have on blogs.
I wrote about this a while back when I took the blended rss feeds of 5 social media guru blogs and their combined corresponding twitter feeds and ran each through a text cloud generator, and then compared the two clouds. The twitter cloud depicted a much more informal discussion about a broader range of topics. I thought it would be interesting to see if the green discussions on Twitter differed from those on blogs as well.
Rather than do another text cloud experiment, I decided to use Yahoo Pipes to crunch together most of the twitter feeds in Kim Woodbridge's list and then sort them by date so they'd create a useable RSS feed that portrayed an actual discussion taking place among "green tweeters."
Since I was looking for more of a discussion than a news feed, I didn't include the twitter feeds like BBC News or anything in which every single tweet starts with "New Blog Post." I also added a couple of people I thought made sense - Tim Hurst (@ecopolitologist) and Maria Surma Manka (@mariaenergia). I hope this starts a discussion on who belongs and who doesn't - I don't claim to be right on everything...
This remains a work in progress, since I'm still learning Pipes. I may have issues with the sorting, but it seems to be working OK for now, and I added the feed to my sidebar. Here's the pipe I made public on Yahoo Pipes, so feel free to take a look, offer suggestions on who else to include etc:
Here's the current list of "Green Tweeters" - I'd love to see this grow...
