This should probably be in a general forum but, since I usually post in this one...
I don't read solicits. I don't actively check what's coming (Diamond/Previews etc) but will have an eye out, somewhat passively - preview-threads, for example. So I usually read an issue going by what's come before (in an arc) rather than a 'next time in' sort of thing. For example, the new Trinity book - I had no idea that the big yellow dude and the green lady were going to be in it (I still don't really know about the big yellow dude, it's just some posters mentioned him being mentioned in a solicit, but, given the reveal at the end of issue 2, I figured that was who the green lady was referring to).
Anyway, how much do you think/feel/believe you're affected by solicits (and how disappointed are you when what you get isn't what was solicited (no poll on that one)?
