Exactly and it's what you said earlier that got me thinking.
Paola and I help authors find agents all the time. And we always tell them, look at other books similar to yours, find the authors, and look at their agents for possible leads.
So.........I'm thinking, could that work for Tapas. Find comics with a similar "feel" as your own, subscribe to them, and post on their wall that you love the comic - and see if others appreciate the post and immediately go to your own - and subscribe.
Hmmm.
