The innovations around Twitter just keep on coming, proving, if nothing else, that an open platform is the best spur to innovation there is.

Yesterday I noticed a couple of posts like this one which point to a simple discussion thread created by an application called Tiny Thread. It’s a simple but powerful add-on to the Twitter platform.

Meanwhile, the energetic Dave Winer posted about his mash-up with Disqus which allow you to start a discussion from a single thread.

And yesterday I also read about the latest iPhone app to take advantage of the open Twitter APIs, Twuner, which will read you your tweets on your iPhone.

Twitter may be struggling for a business model, but it is a beacon for innovation in the tech space second to none at the moment. Keep your fingers crossed they remain independent.
