I used to have a feature on my site that let you choose to be e-mailed when someone comments on a post if you give your e-mail address. In the notification e-mail you'd get a copy of the comment that was left, an 'unsubscribe' link, and so on. In fact, all the code for this is for the most part still in my weblog application code.
The main reason it's not enabled now is because I don't want people getting my comment spam (and flames) in their e-mail, but the only way around this is for me to approve comments before subscription e-mails go out.
Should I re-enable subscriptions despite the fact that people might occasionally get spam or flames? I suppose I can have a disclaimer that will tell people to beware. What do you think?
Update: Ned just implemented this feature.
