HTHT is pretty much rated for general audiences throughout, as long as those general audiences can deal with the sophisticated vocabulary and some emotional intensity. The same is not true of these links. A number of them include strong langauge, extreme violence, sexual content, alternative lifestyles, and other things that would not be ideal to show to your six-year-old child or your fundamentalist neighbor. Welcome to the Internet. The links range in severity from "I'd show this to my most squeamish uptight devout Mormon friend" to "I considered not publicly admitting that I read this", but you may or may not agree with my ratings, and not every cell will have items on each end of that spectrum. It's the Internet; you know the drill.

I read a ridiculous number of comics and blogs and serial fiction projects and and whatnot. I am not linking to all of them here, because that would be outrageous. I'm only including the ones that I like very much, have been keeping up with for a while, and consider to be genuinely high-quality (not just something that tickles my idiosyncratic fancy). I am linking to some things that no longer update. Apart from the category divisions, these are in no special order.

More Alicorn	Luminosity is an AU Twilight fanfiction project. It's better than it sounds. Elcenia is a fantasy series in progress. Improvisational Soup is my food blog, which focuses on easily variable "recipes" that often call for no specific measurements at all. All of the food I describe there conforms to my own pescetarian diet ("pescetarian" means vegetarian plus I pretend fish are plants). Ensorcel is an interrupted, presumed dead, spellpunk webcomic that I wrote and my little sister Hoseki illustrated. She ditched the project and presently has no intention of returning to it, but the archives (and our witty commentary interchanges) remain visible. Syzygy is an interrupted, presumed dead, fantasy webcomic that I wrote and drew until a backup failure resulted in the temporary loss of the files. My subsequent emotional break from the story meant that even after the images were recovered, I did not pick it up again, but the storyline and a half that were completed are available.

Khaos Komix is a multi-threaded romance consisting almost entirely of alternative-sexuality characters. Lackadaisy Cats is a marvelously drawn comic set during Prohibition, and also, everyone is a cat.

Saturday Morning Breakfast Cereal updates frequently; the humor is lowbrow, the topics run the gamut. Skin Deep is a richly illustrated group of stories about mythical creatures who hide in plain sight. Skin Horse is about a team of government agents including a talking dog, a zombie, and a transvestite. Something Positive is a slice of life with a unique ratio of snark to gelatinous cat. Its sibling comics (available from the same site) are also recommended.

Subnormality defies description, but it has the Sphinx in it.

Narbonic has ended, but was about a mad scientist, as well as her employees, test subjects, rivals, and casualties. One Over Zero has ended, and was a relentlessly self-referential comic with considerable philosophical depth.
