Value of feedback to users
“That’s one of the big weaknesses of [blogging], the only way you know if anybody is reading it is if they take the trouble to reply. Without that you have no clue who people are…it’s largely unidirectional.”
—Subject quoted in Yardi et al., CHI 2009
47 1 September 2009
With S. Yardi, S. GolderGeorgia Tech, Cornell
48 1 September 2009
Diverse feedback is valued
“After starting my blog, it was amazing to me how quickly I met other people, especially across different business groups… I would post something on my blog and a week later I’d get an invitation to present on it.”
