I am re-inventing the blog wheels, and am about to implement new comment notification features.
I already know that I’d want the admin (me) to receive emails when new comments was made or waiting to be approved.
But, I’d also like the commenters to receive email notifications when they’ve chosen to subscribe to a topic.
Or maybe I shouldn’t bother?
What would you do?
I planned to let the notify checkbox be checked by default: the users are receiving an email when a new comment has been made on a per post basis.
Is that a good idea?
I’ve considered using cookies, or let it be off by default, but then people need to remember to turn it on…
They would receive an email that the post has received a new comment, with a small note at the botttom saying that she (or someone pretending to be she) has requested to be notified.
And then a link to cancel the subscription…
The next time the person visits the blog and posts a new comment, unchecking the notify box, she would be removed from the list of subscribers.
Should I bother with this?
Or should I just put a link to the rss feed?
It it too intrusive, or a good feature? 
Most places don’t do this, so maybe I shouldn’t?
But I actually liked to be notified when I visited a blog which had this feature.
The last thing I want to do is spam people.
So I’d probably put a cookie on the users machine so that the form remember the state of the notify field.
Maybe.
Have you experience with this, or ideas, comments - I’d like to know.
