Dear Ms. Snark:
What's your opinion on ebooks? Do you look favorably on them, or do you think publishing one is a potential determent to a writer's career?
ebooks are books read in little e-book readers, or online. Why would they damage your career? Are you confusing e-books with POD? They aren't the same thing at all.
E-books, acquired and edited by someoone-not-your-mom, is a legit publishing credit. They don't sell vast quantities but they aren't anything to sneeze at either.
Here's an example of a legit, e-book publisher: Linden Bay Romance.
