I just instituted it today.  It can be modified somewhat if people want but I thought it would ensure quality postings.  Twenty words really isn't all that much.  If the average sentence is about 12 words, then this requirement means people have to write about a sentence and a half worth of writing.  If people think this is unfair I'm open to suggestions.  However, I hope people would agree on the ultimate goal of this.** Ok I just saw your post on the "what is this?" thread.  If you click on the "quote" button it will include that stuff in the count (see what I did in that thread).  **
