There are other comics that I've read big or small portions of and enjoyed but haven't gone back to in ages because I simply forgot (or forget) (Hot Mess ((Still on the fence about this one, but I like the idea behind it)), Power Puff Girl Doujinshi, Sugar Bits, Grim Tales, Ever After ((The Snafu ones I used to read all the time, but slow updates and forgetfulness made me drop them)), Girl Genius ((I really wanna read this one but never get around to it))) about them or they stopped being updated regularly. Nothing wrong with them at all--I just forget to check them.
Secret Asian Man is the one I'm saddest to have let go of--it used to be on Comics.com but then it moved to a separate website and was updated Sundays only.
I've read some of Ctrl+Alt+Del, Gunnerkrigg Court, Real Life (I think I also read a comic that was related to it or linked or something), Red's Planet, Dark Legacy (I've read a LOT of this one), A Softer World, and Looking for Group, but I only archive-binge for certain comics (QC and GWS), and it's hard to motivate myself to do that for comics that are hard to remember about. I like these comics quite a bit, but I have enough on my plate, so it's hard to justify getting caught up so I can read it regularly.
There are a few comics I've read a lot of but grew to dislike quite a bit for one reason or another. That makes me sad, but I don't want to waste my time on comics I don't enjoy.
And does The Comic Curmudgeon (Joshreads.com) count? I read his stuff religiously.
I also read the daily comics in the newspaper, but I'm ages behind. My family has been so kind as to hold onto them for me.
