Continuing yesterday’s surge of interest in the dogfood experiment, I’m happy to offer the roundup of rapid responders. Since the responses were unfortunately divided between two blogs, one of which was moderated, the relative order of responses given below is approximate, although I believe the overall timeframe to be accurate.

I probably don’t have to say this, but let me know if you believe there are any errors or omissions here.

Note that this is a more detailed version of the list of respondents posted the day after the initial test, and adds some companies that have commented since.
