The analytics for my blog look very similar to this. A 24-hour period of intense activity followed by basically nothing. I had a post reach the front page of Hacker News [1] and /r/programming [2]; it got around 10,000 hits. I reached the same conclusion about HNers vs. redditors: HN stays longer and interacts more, but sends fewer hits.
