Hey. Yeah I couldn't delete the comment, so replaced it with a dot. I deleted the comment because I accidentally added it as a separate comment instead of a direct nested reply to your comment (see above). :)

Deleting might be useful, but perhaps only if doesn't have any replies itself, otherwise it could be tricky/confusing? I would find it more useful if I was notified of a reply to a thread I had commented on, or was watching, or just every thread. i.e. I only saw your recent comment as I happened to check just in case you had replied. I would have entirely missed it otherwise.
