I'm not wary of e-publishing; I prefer print publishing because I have a number of issues with e-publishing:

1. Plagiarism. Always a problem when you post anything online.

2. You have to know where to find the book (find the site, hunt through the site, etc.). No matter what, you aren't going to have the same visibility as you do with a book in a bookstore.

3. I want to be a best seller or higher. At present, that doesn't happen with online books.

4. You miss a portion of your audience. That portion comes in two parts, the people who aren't online (and there are still some) and those who don't like to spend a lot of time online.

5. There is still an elitist attitude about publishing online--that print is better. Unfortunately, some of this viewpoint has been earned. I've seen writers toss their novel up on a web site either in a desperate attempt at getting discovered by a publisher or figuring that since no one will publish it, they might as well share it.

6. Payment. Largely, web sites selling anything are still struggling to find out how to get people to their site to buy something. We get ads all over various web sites, annoying pop-up ads, ads in email messages, spam--you name it, we get an advertisement. And they still haven't figured out how to draw customers in! So you can imagine that this same problem may impact some of the e-publishers as well.
