Bear in mind as well that by most webcomic standards, Questionable Content does have a fairly sizeable regular cast and a limited amount of space to work with. Now each character is going to be unique, but at the same time, each fills a certain role and unfortunately, there will be a certain amount of overlay. For example, in the case of the library staff, you have Marten - who might be considered the straight man to the shenanigans going on there. You have Tai - the sometime stoner/sometime level-headed boss. Claire - sometimes prone to acting rashly and something of a jerk at times. Emily - Well, she's Emily, 'nuff said. And finally, you have Gabby - Who compared to Emily and Claire, is the straight man of the interns. So one might imagine that strips featuring just her and Marten might be relatively boring. This isn't saying that Gabby was a poorly created character or simply written out, but I can see from Jeph's perspective why she might be difficult to work with and there's only so much you can do with a character before you have to give them a rest. You can see with quite a few other characters, most famously Raven.
