Well, that's exactly the point I am making: Compared to the commercial books, Pediapress books are so cheap that people can afford to buy the latest editions to stay current. (<a href="http://pediapress.com/books/">http://pediapress.com/books/</a>)<br>
<br>In any case people can download the latest pdf each month and read them at leisure.<br>This only involves the cost of downloading. This would be especially useful in the initial months when the wiki is being re-written at break-neck speeds. (Once the wiki matures, the user won't need frequent upgrades).<br>
<br>Ton, there is no way to keep the authors of the commercial books happy on this count. Thanks to the pdf/odt extensions, the wiki-based books have acquired a natural strength that no commercial book can match. <br><br>
The only way you can avoid a competition is NOT to let users download the latest odt/pdf versions (by not installing the pdf/odt extensions mentioned in my previous post). But I don't think that's fair to the wiki readers.<br>
****<br>The original thread started with the proposal to have a quarterly magazine.<br>(Nothing to do with wikibook vs commercial books on Blender).<br><br>yet it is worth thinking about this aspect.<br>
