I came to see the following pages accidentaly, but it is nice please check these links, they all are talking about "The Under Construction Page". There are too many people who are against the under constrction pages like Gordon Kindlmann You can find a list of people who are against this here

They says

"Under Construction Images are bad. They are stupid, pointless, and take up unnecessary bandwidth. Everyone knows that all Web pages are under construction, so why do we need to state it so bluntly, let alone use images to illustrate our incompetency?"

And there are many who support this like conveyor.com. this site says that "This Site will always be Under Construction !". Howz that?

Here is some other pages

jjknuutt, acme, donotender

So much about a simple Under Construction Page ?????
