I love getting comments! I check my comments often; as the blog owner, I can check them directly through HaloScan. This makes it easy for me to find new comments on old posts.
Unfortunately, while the HaloScan page displays the most recent comment on top, it does not link the comment to the original post! So please do me a favor: if you're commenting on an old post, try to mention the date, post title, or topic of the post so I have some idea of the context for your comment.
