10/24: Man Three
Washed Ashore is a comic by the same artist who makes Comet 7 (a comic that I was not overly fond of) and Kristy vs. the Zombie Army, which I am pretty fond of.
Training Wheels is pretty good, and it is part of many, many comics in what is Snafu Comics, which I note has a collection of comics that are mostly fan-fics. I have not read any besides Training Wheels (which is pretty entertaining, if mostly lacking in the consistency it tries to attain, sometimes) and the pilot comic Snafu, which I only read through the archive of after having seen the most recent update, which is awesome. The rest of the archive? Less so.
Very similar in target audience, Internet Superbuddies lacks in many areas, notably expressions on characters that actually change, but at least 1/3 of the comics in the archive are smirk-worthy, and many 2 or 3 of the 55 may actually make you laugh. However, if you don't have time to waste looking through mediocre sprite comics, you can always read 8-Bit Theatre.
Looking through my bookmarks, I found Pictures for Sad Children, which is a bizarre and great comic that was only just starting when i finished reading the archive, and am just rediscovering.
Looking back at Post Secrets, I am reminded of Playing with Dolls, another comic by the wonderfully talented Spike, who draws and writes Templar, Arizona. Along with A Softer World, these comics often have a very cynical view on relationships and some interesting insight on the people who get into bad ones.
