I remember brewing a few recipes from that site when I was starting out, and they didn't turn out well. Now, going back to my notes, it wasn't 100% my lack of experience brewing, but the recipes were just wonky.
My preference now is to always grab recipes from either a source you trust or at least a source where people can post feedback. I usually start at homebrewtalk.com's recipe section or Jamil Z's book as a baseline. I usually begin tweaking and asking questions once I've got a proven recipe as a starting point.
