Most webcomics are pretty geographically centered around where the main characters live work and play. This makes adding characters easy, since they can come and go as the creator pleases. The other model is that of a travelling party, like in an rpg.
In my comic the central narrative is about a single character's journey. There is a point in the story i have in my head where he meets a fellow traveller, but for it to flow and make sense, that point is many weeks away. In the meantime, I've already introduced two characters who went away and won't be seen at least for a while. I don't want to keep bringing in secondaries and then sending them away, but I don't want to rush in the next long term character either or try to drive the plot without anyone else in it. Any ideas?

Ad Grunts is a new strip about advertising. Slickly drawn and funny (two words: Tampon Transformer) this is a promising rookie.

Also creators, J.Cheng & H.B.Flyte, have done a nice job using the blogging software, WordPress, to run the archives for their site.
