Let's be honest. Twitter is an extremely creatively lazy way to waste time. But it's also a very convenient way to communicate with peers you've might've never had the opportunity to communicate with before. Case in point: Brian Winkeler. He and artist Dave Curd have an amazing property entitled BASTARD ROAD, which has appeared in the (Eisner Award winning) anthology POPGUN from Image Comics.Another good thing about Twitter, it give me another forum to peddle my wares (since I still refuse a facebook account). Brian was cool enough to order my hardcover. I in turn included an original sketch of his characters. BASTARD ROAD is truly an amazing, fun read. I definitely cannot recommend high enough. If you liked R. Grampa's MESMO DELIVERY, you'll really dig their book.
Brian was so cool, he even put together the above snapshot for his Twitter Followers.
