An excellent Taxonomy of the Logical Fallacies is available HERE.
Skeptics rely on sound logic in the quest for Truth. Of course, logic also comes in handy when debunking false claims and exposing weak ones.
The site comes complete with a "How to Use the Taxonomy" guide which explains the layout and color code. What I really like is that every fallacy, such as post hoc ergo propter hoc, is linked to a full page description with examples.
