For me it was a segment about steampunk in this tv show "AOTS" and they happened to show the comic and the website it is on I'm so glad that I found this because, I was looking for a good graphic novel to read =D
Edited (sorry) for focusing reasons. Someone twitted about it (I think it was digitalyn, or maybe Warren) or I must have read about it on Facebook. Actually since I first answered, I can't really remember: weird!
My little brother was talking about Whitechapel (as a great community to meet artists/writers/geeks) for a long time, before I ever figured out it was a webcomic as well. Somewhere along the way made the connection that Warren was writing some ongoing thing... Stumbled in about March of this year not really knowing what to expect.
I found it from the LJ which someone pointed me at during a phase where I thought trolling certain ljs with a modest proposal and babyback ribs recipes was funny. Okay so I still think its funny but haven't acted on that in a while. I had no idea who Warren was beyond an interesting fellow; I liked his Falconer stuff, and the music he put up on the lj, started reading the .com, found whitechapel, and started reading FA from around the beginning, though at first I was pretty much afraid of everyone here. I got snagged on FA from the promo-pieces before the comic popper went up. I still think they're lovely.
looking through various online publications on steampunk found an article on www.coilhouse.net. found it to be extremely addictive cant wait to see what comes next and need to get myself some merch...
A comic series called Sin Titulo had a blog entry by a reader who mentioned FreakAngels as another of his regular must-read favorites. Well, he was right! Isn't the internet wonderful?
