For almost ten years now, whenever I’ve been involved in an activity that involves Twitter conversations I’ve headed over to TAGS and set up a copy to collate tweets and produce visualisations like the one above. So earlier this month, as I was tweeting to the #ETMooc2 hashtag, I was devastated to realise that it was now broken (I knew it was going to be, but I didn’t want to believe that it had happened). I’m too upset to explain the reasons why, and anyway Alan has already done that, I just wanted to say how sad I am that TAGS has gone. My PhD thesis about serendipitous learning was shaped by my ability to collect #CLMooc tweets easily and see what the community conversations looked like, my research into lurkers with Aras, AK and Len used TAGS and similar apps.

So a huge thanks to Martin for all the TAGS. It was great while it lasted.
