When you’ve got a dialogue going with someone on Facebook you most likely find out via an e-mail notification if something has been replied to.
Ding, you’ve got a message telling you that someone has replied to your status or conversation. Now click the link, go log in, type your reply, log out…and get an e-mail 10 minutes later with yet another reply. Repeat the whole process.
Because now Facebook supports replying to comments right from notification e-mails!
When you get a notification, just hit Reply in your mail client, reply to the comment at the top of the e-mail and send! Your comment will post to the relevant conversation and you don’t have to do the log-in shuffle anymore!
