In reply to eBook Font Suggestions Sought:
Dedicated e-readers (Kindle, Nook, Kobo, etc.) have their own built-in fonts. Using the built-in fonts, supposedly optimized for the e-ink display, is encouraged, and embedding fonts in an e-book is discouraged.
To discuss this with some passionate amateur e-book creators, try the mobileread.com forums, and post in the "Workshop" or "ePub" forum. You can also get sample ebooks in several formats from the library there. The proofreading and formatting far exceeds what you find at PG, and the best people there do better work than I've seen from the big publishers.
