Email notification of comments based on age
Short, concise description of the idea
Provide an option to make email notification of comments added to LJ entries conditional based on how long it's been since the original post.
Full description of the idea
With this feature, an LJ user could specify that they want to receive e-mail notification of comments only if the original entry is older than, say, 24 hours (the time could be adjustable). This would be helpful if, for instance, the user generally pays close attention to their most recent entries anyway, so an e-mail notifying them of a new comment would be superfluous, whereas a new comment to an older entry is more likely to be overlooked and an email bringing it to their attention is helpful.
Similar functionality could be added for replies to comments made in others' LiveJournals, and to entries and comments in communities.
