Post here the link and description of the webcomic you always read! Completed Webcomics have an ending, Still Ongoing Webcomics should be self explainatory - there is an ending, but it is still being drawn out and posted. The Daily/Plotless Webcomics either post daily a new page or/and have no plot at all.
Here's what I read (Yes, these are all on my 'Favorites' tab):
Complete Webcomics
-Cool Cat Studio
The beginning is random-ish, but starts to form a storyline near the middle.
-Aoi House
About these two guys that end up joining a yaoi club and the funny things they go through.
Still Ongoing Webcomics
-Grim Tales
If you like The Grim Adventures of Billy & Mandy, this is worthwhile to check out.
-Sugar Bits
Neat storyline, nice art, original.
-Naruto: Heroes Path
If you like Naruto, this is worthwhile to check out.
-Khaos Komic
This is about all kinds of love, boy-girl, boy-boy, girl-girl, and transgender - the complexities of it all.
-Last Blood
This is about vampires and zombies, the extinction of humans and pairing up with the vamps.
-Marry Me
Very funny and entertaining. How a superstar singer ends up marrying a normal guy.
-MegaTokyo
Very well known and popular. 2 guys ending up being stuck in Japan and all the crazy shenanigans that end up happening. (Starts off being really random)
-Patches
A world that each person is born with a certain special patch, and the one you are meant to be with has the same patch. But it's difficult for the ones that have the unique patches. (She hasn't updated in a long time - very long hiatus)
-Penny and Aggie
A very long webcomic about high school kids, love, hate, and what is right. Once you read more into it, it's entertaining.
-Red String
It's about love, true love. Have you ever heard about the legend about the red string? (If you haven't, you'll be confused) But it's from a Chinese legend, here it is:
"An invisible red thread connects those who are destined to meet,
regardless of time, place, or circumstance.
The thread may stretch or tangle,
but it will never break."
-The Phoenix Requiem
It's has a very nice storyline, makes you wonder. A mysterious disease killing many people, the belief of spirits and a man that is able to connect with them.
-Dreamless
It's very interesting, about an american girl and a japanese boy that are able to experience eachothers lives when sleeping.
-Powerpuff Girls Doujinshi
If you like the Powerpuff Girls and Cartoon Network, this is very worthwhile to check out, characters from Cartoon Network all together.
Daily/Plotless Webcomics
-Saturday Morning Breakfast
Very random, some odd, some geeky, but funny. And it's a daily comic.
-Sinfest
Very funny, shows lots about God, the Devil, Buddha, and randomness, controversial things sometimes. And it's a daily comic.
-Kawaii Not
SUPER CUTE, everyday things and what they would say if they could.
-Three Panel Soul
Just geeky, funny, real life incidences.
