@Coley It totally would.
As for SCBWI. That is a good question. I think that if I hadn't started writing a story I probably would've let my membership lapse this year. Last year was the first year I had joined, and as an illustrator I didn't feel like there was a lot of support, especially in my region. I went to my regions spring conference last year and I'd say about 90% of the programs were geared towards writers. There was one workshop out of sixteen that was specifically for illustrators alone. Since I'm writing now, and am a total rookie at it, I think that I will get a lot more out of the conference and the meet & greets this year. I went to several meet and greets last year thinking to meet other illustrators and there were only writers. Fortunately I met a great art friend through svsforum that lives near enough that we can have a monthly art day.
I'm going to this years spring conference and possibly the summer convention in LA, and if I feel the same way as last year then I will probably not renew next year. We'll see.
The SCBWI TheBook is awesome, but not the only source of contacts.
