It's come to my attention that my e-mail notifications somehow got turned off (despite the fact that I haven't messed with those options in months), and I tend not to revisit entries unless I get a comment, so... Sorry if it seems like I've been ignoring anyone? :D?
And, yeah, I just felt like using this icon.
Note: This doesn't have anything to do with LJ not sending out notifications (maybe?). Mine were actually turned off.
