I posted the "soft trial" piece here on Monday morning, reaching people directly and via RSS. Five people have commented in two days.
I posted a similar piece on the C&I Update blog on Tuesday,presumably reaching people mostly via RSS. One person has commented in one day.
I posted a much shorter piece on the Topica mailing list last night, reaching people via email. So far, 18 people have commented in 12 hours.
I already had a Perspective written on "conversation" and various internet tools (and claims as to how they support). This datapoint will probably modify that Perspective slightly.
