Well, I used to read Megatokyo. It's still on-going I think, but the plot (from what I heard) has become kind of convoluted. lol I used to love it back in mid-2000s but I stopped reading it for years now.
I also loved Alternate and Todd Allison & the Petunia Violet but the author has gone awol and never came back to their western audience, due to some disappointing issues regarding their kickstarter and personal life. Too bad.
Anyway, there were quite a few comics I liked on smackjeeves. I still have an account there, and I think only 2 comics from my list are still updating there.
