My personal problem with HN is all the different links with titles that half of the time do not really cover the contents. So I spend to much time opening links and wait valuable ;-) seconds just to discover it was unnecessary. Or skip links which might have been very interesting.<p>So to speed things up, my ideal reader shows not only the link, but also at the same time a screenshot of the page behind it and preferably even (part) of the actual text. That way I can judge really quickly if its worth opening and reading the page.<p>I would certainly spend money on that one.
