That makes total sense for your blog -- getting one tip a day in your RSS reader is way better for learning them than looking at them all at once.
However, I don't think it makes sense to post it on HN. If all the posts on the front page were little snippets, the conversation would quickly degenerate.
I think useful content is useful regardless of length.
Also, TONS of crap gets submitted to HN. You're seeing this because it was voted to the front page. I don't think I'm affecting the quality of conversation negatively.
