Can some one please share all the things you can write in a book to have the readers participation. I know some of them are newsletter, polls, Rss feed, subscribe to channels (youtube or twitter). However, what else can you say and add into for readers participation and involvement?
Any method that generates user generated content will do - like allow visitors to leave comments about your blog, make their own blog or wiki in your site perhaps, anything that promotes or retains visitor involvement and encourages visitor participiation like surveys and polls etc.
forgot to mention this: NOTE: I am ONLY talking about an EBOOK that you can read on your PC or mac or linux computer.
