First thing, this is going to be a wonderful resource and something I'll look forward to with anticipation. Now I'll be able to be a more regular reader of your mag.
The pdf downloaded relatively fast and the print quality looks good. I will typically use this option as I like to read on the GO-train.
The online version works well. I like the page flip and the resolution is good. I would not recommend reducing the resolution in any way, shape or form. Especially with people now going to larger monitors both on their PC's and laptops. My suggestion is that you provide an option to the subscriber / reader to access either a high / med / low resolution version - depending on their system capability. Low resolution may work for those accessing through their iPhone or Blackberry, for instance, whereas, high resolution would be for those with a media PC, reading on their 50" television screen.
Some other suggestions:
1. Get rid of the green screen background and black on green font on the welcome / launch page. I'd suggest either a black background with white font, or any darker background with light font.
2. The "next page" arrows should be made larger if possible and the skip buttons made smaller.
3. The skip buttons should skip you to the next article within the magazine i.e. those listed in the table of contents. If you really want the reader to just get to the front or back of the mag. with these buttions then add an specific "front page / back page " button.
Question: Would you consider providing a pdf version available on your site for back issues? If at least, going back to Dec/Jan of this year but it would be great to be able to download and keep old issues as well?
Looking good - all the best with it.
