For the record, I have no problem with Twitter. In fact I find it invaluable sometimes. Great way to crowd-source info/news, share my work, chat to other artists, and generally a good water-cooler replacement for a freelancer without a bunch of co-workers to talk to.
But I also get frustrated with 140 character arguments that take place on it and wish people would think a bit more before they tweet (I'm probably guilty of not doing so myself though). There's so much room for misunderstandings, bizarre trolling/name-calling, and all sorts of behaviour that goes against the "say on the internet what you would say to someone's face" rule. Still, even worse than watching that happen is when you see "Twitter-storms" being talked about as if they are news. A particular portion of Twitter being offended or having heated discussion does not a story make. And it's usually a result of an article fishing for traffic anyway.
This comic wasn't in reaction to a particular story but a reaction to a few months of seeing these things happen and generally losing patience with it.
I added a wash of watercolour on the original to get some new colour effects for the panels in space or inside the body. Think it worked nicely and I like the pacing of the piece. Was a nice contrast to the heavy-on-the-text-and-information comic from the previous week.
