End of an Era Time: From Mai to Blade of the Immortal

That era extends from my early college years at UCSB to this month. (That is: a long freakin' time.) Dark Horse just ceased publication of BOTI in comic format, and will now only release it trade paperback. (In a format that doesn't quite match the tankoubon releases, but are pretty close.)
I don't know if there are any manga that are still published in single issues of comics anymore. It doesn't bother me one way or the other. I like the trade paperbacks, too, and I'll continue to support Hiroaki Samura any way they let me.
