The thing that has always made me hesitant to use Instapaper and services like it (in particular the ability to read stuff on an e-ink reader later) is for me a major part of the value of most of what I read, is the comments on HN. When you move the content to a reader device, you lose that. Has anyone though of a solution to this other than read the article and then hop on HN and try to find it?
I personally find that there's nearly no overlap between articles with comments (at least those which I'm interested in) and those I read on Instapaper. Think that's because I don't tend to put short "news" items on Instapaper, just long form articles.
