I'm pretty pleased with the response since textivate was launched. (Updated 19th Sep 2012)
Notable mentions include:
Create Instant Interactive Text Based Activities from Nik Peachey's QuickShout blog. Some nice comments here beneath Nik's very positive review. This review in particular was widely reproduced and re-blogged, scooped etc...
Top Technologies for Language Learning - the Tools section of the Speechy Project website. (Gold medal / 1st position last time I looked). You can see the full review by clicking on the image, or click here.
Using textivate.com for simple interactive tasks from Baiba Svenca's EFL blog "B's Life with English" - a great example of one way of approaching the teaching of a text using textivate.
"textivate" has potential, BUT... in which Larry Ferlazzo says that the downside of textivate is that it doesn't allow teachers control over things such as gapped words. I've replied to him on the blog post, if you're interested.
Textivate - a review by Steve Smith of frenchteacher.net - this was the first review to appear, just one day after textivate was launched, and I think Steve's assessment of what textivate does and how it compares with TaskMagic is pretty good.
