It's a good thing. But instead of discussing on [[en:Wikipedia:Pageviews]]it should be done in [[meta:Pageviews]]
You should also check the work already done by LeonWeber. It's live in de: The JS code is in http://de.wikipedia.org/wiki/MediaWiki:Pagecounter.js The tool is running on the toolserver. http://pgcount.wikimedia.de/ is an alias.
You can see the top100 queries at http://tools.wikimedia.de/~leon/stats/pageview/temp.php It's beta but will be released in the next days. He'll implement it for other wikis... after vactions.
Only showing top doesn't reveal lees seen pages (and remember that seen != watched)
Another problem could be avoiding spamming the view list.
