I've been in rookie webcomic teams a couple times (although neither of them got to the net, even though the second one had around eight strips finished), and I always find it funny that the biggest argument you'll ever have has nothing to do with what art style you're going to use, whether or not you'll have story arcs, etc. It's the name. And man, my webcomics had some bad first-idea names. Here are a few examples:
Warez Waldo
ROMmates
I Think She Gave Me Pixelitus
Go After Monday, Energetic Robot! (G.A.M.E.R., get it? Oh, god...
)
The final names were eventually Console Wars and High-Rez. The former lost its artist in pre-production and the second comic disbanded from inner conflict. I'd do my own but my art is crap; I mostly write. Anyway, feel free to pitch nonsense webcomic ideas here and make fun of the examples above.
