All strips appropriate for anyone to check out (unless otherwise noted).
http://strangecandy.keenspace.com/ - shoujo l33tness
http://amphetamine.keenspace.com/ - just starting over again, pretty good premise, updates too slow.
http://www.north-comic.com/ - should be good when they start up again. Daryl is one heck of a drawer. Check out the old NoRTH at
http://www.north-comic.com/NoRTH/index.php?comic=1 for...um...interesting stuff. Other than the last drawings there, it's fairly appropriate for any age.
http://www.exploitationnow.com/ - absolutely NOT for children, beware. Very dark humor. Very, very. Has gotten very serious lately, although it's backed off somewhat.
http://www.eversummereve.com/ - more shoujo goodness, even better drawing. An interesting story, although pretty slow (think Gasaraki, and you've just about got the pacing).
http://selfinsert.keenspace.com/ - otakus inserted into anime. Enough said.
http://www.wintercomic.com/ - pretty interesting comic, but Soup hasn't really updated it in a long while...
http://www.montroseacademy.com/jar/ - Um...three guys and a jar. It's...well, difficult to describe.
The other one I'd post is no longer hosted by the author, and although it's still up (someone took all the credit for his work), I won't post the link.
