You can get your visitors to contribute to your site by asking them to submit their own writings, experience etc.
You made an excellent point regarding reading from a screen. I hate this myself and tend to print out the more important things that I find, then I can read the content without straining my eyes. You can offer your readers the same content in a PDF file, this will allow them to easily print off what you have a written. Place a link at the top & bottom of each page saying something like 'download this article in PDF format'.

Look around for sites that are doing something along the lines you want. How does the site owners introduce themselves? Take a look at what they are doing to please their visitors, can you do the same?
For one thing, you are asking all the right questions.
