Oh hey! I'm guilty of that too!
Background People and The Landfill haven't updated in months! That's probably a new record. ;-;
And me, who used to be a frequent poster! Shame on me....

As much as I really hate to say it, I don't think I'll be able to continue writing for people anymore. It's really hard to keep up with school life (which is unbalanced as heck) and posting deadlines. Heck, I don't even go to the Forums anymore.
Writing just gets harder and harder to fit into my daily routine, and it's driving me nuts. Writing works as something like a therapy session for me, and not being able to do that drives me up the walls. Literally.
I can probably count on my fingers all the ideas I've come up with and died in my head because I couldn't write anything down. It's just really disheartening, having this and being in the midst of all of you creators pinging ideas off each others' heads.
I'm probably going to be one of the hordes of would-be writers banished to the shadow realm for not being able to insert writing in their lives.

My answer to your whole webcomics dilemma? Absolutely impossible.
As long as there's someone inspired enough to pick up a pen, or a tablet and start expressing their feelings out in ink, paint, or even in pixels, there's going to be webcomics.
