User talk:Peak/Preamble

The first sentence of an article generally gives a summary indication of what the article sets out to establish. E.g., Jumping spiders are spiders that capture their prey by approaching fairly near and then springing upon them." The first sentence of the Preamble does not do that, and it would cost the reader some time and frustration to discover a main thread.
