Thanks to some help from James, I've gone ahead and rated this site so that unsuspecting (and unsupervised, I'd imagine) kids won't have to be traumatized by something they might read or look at here (or so the ICRA claims).
I have mixed feelings about ratings. Personally, I don't think that they work, and are no substitute for supervising your children. Furthermore, I think that increasingly easy access to the internet makes it all too easy for kids to find unrestricted access. But, for parents that are trying to do the right thing and living in a constant battle with television, music, and the internet to raise their kids... well, if rating my site for content in any way helps, then I have no problem giving it a try.
Here is how I've chosen to rate my blog (with samples of material):
I decided not to label the above as being in an "artistic context," even though I personally believe that to be the case here. Given what I know from having a 13-year-old nephew, this site is positively tame compared to what kids are exposed to at school every day... but whatever. Just doing my part to preserve public decency!
(Trying to type that last sentence with a straight face was near impossible!)
