It's really me. :)
But then, any decent troll would say the same thing, so this is going to have to be one of those things you take on faith—or don't take on faith. I really don't mind much either way.
I do try to use 'jimbutcher' or 'jimbutcherauthor' as a username as much as I can, because I'm on a metric fuckton of various sites, and I just can't keep track of all the usernames if I don't group them into a fairly small number of variations. Back when the Dresden Files was still a fairly tiny series, I used 'harrydresden' as a username a lot, but these days I have trouble finding a place where it isn't already taken. For gaming, I generally use a Dresden Files character handle, or else my standby of "Heckhound."
And why the hell wouldn't I actually be here? I will fly my nerd flag alongside anybody's. :)
To answer the above Alera question, the Canim have indeed been the most successful survivors of Alera's genetic cuisinart, but were essentially isolated on their continent due to the high risk of getting eaten by sea monsters if they sailed around on the ocean too much. The Icemen have actually been around the longest, but they've essentially maxed out their culture up there in the wild arctic. You don't really develop railroads and opera houses and senates when you get everything you need out of life from the carcass of a small-tonnage whale.
And yeah, if I go back to Alera, a steampunked version of the place, set after Gaius Tavarus's forced integration of Aleran Furycraft with Canim engineering has had a few centuries to develop into full blown airships, railroads and steam-powered velocipedes. I think that one would be a lot of fun. I also had an idea for a series set maybe 20 years later, that would basically be a PI-story structure starring the first Marat to bond with one of the Canim, a pair that essentially wound up blood brothers who were incapable of ignoring hopeless but just causes and who continually got into increasingly deep levels of trouble.
I'm actually planning a new steampunk series, as yet unnamed, but the characters in it are really working for me, and I plan to write up the first book of it as soon as the Cold Days manuscript is done. It's sitting at an estimated 77 percent complete right now, so I'd better get back to the salt mines. :)
I'll try to drop in every so often to answer questions and whatnot. :)
