I have found that sometimes when you are involved in a swap, not everyone does their best work. They want to participate but end up waiting too long to make their blocks due to different reasons, some ligament and some not, and end up rushing the work. And sometimes of course there are people who just don't care what they are giving someone else. There is always that 1 or 2 percent of people who don't do what they should no matter what you are talking about. So, I guess the point is to focus on those that honor the idea of the swap and make a block that they would be proud to own. And if you decide to participate in something like this, just know that there will be some blocks that you won't be too enthused about using due to workmanship, color, or whatever but the majority of the people will put forth their best work.
