Dave Walden from the TeX User Group introduces his excellent TUG Interview Corner as follows:
"technology is created by and evolves with use by people, and the points of view and backgrounds of the people influence the technology"
The ever growing list of interviewees include Barbara Beeton, Donald Knuth, Herman Zapf and numerous other less widely known TeX users and developers. The interview corner is a meticulously edited set of documents, portraying the full spectrum of the TeX project. Absolutely worth reading and/or browsing through.
