Will CZ articles show the names of the authors/editors? If not, why?
My guess is not, since there will be so many contributions from mulitple authors. At present it is very quiet here, so one author can work on an article without interuption. As more join the project the last draft of any given article will be change quite quickly. However, author contributions will be conserved in the history of each article where every edit can be seen.
If so, will the names include links to "profiles" that inform readers of qualifications? If not, why?
Again the history of each article will give a link to authors user pages. But, I assume the only qualifications that will be visible are those of the editor that finalises any given version. And that editor may not even have edited the article.
All of this is true. For all articles, a list of people who have edited the article (along with links to their talk pages and profiles/resumés) can quickly be established with a visit to the history page for the article. It could take a while if a page has 500 edits, but you can see everyone who edited the page, and what each edit added or subtracted.
Additionally (and this may be the source of the confusion), the template that indicates that an article is approved will bear the name of the approving editor. It will say something to the effect of "This article has been approved by %EDITOR, one of Citizendium's editors in the field of %FIELD". Then you can quickly find the editor who approved it, and with minimal work can find other contributors.
