I try and spend 20-30 minutes everyday going through the "new" tab and up-voting the new submissions I find interesting (think of it like volunteer work). Somehow I tend to up vote Ask HNs more often than posts that are links to website.

that behavior is definitely analogous to volunteer work in one's local community. i used to spend a lot of time on Imgur; now i just spend my time in User Submitted.
