I don't understand your point about scraping Google, do you think they would be bothered by it? If they were they would just add that page to their robots entry and request that you don't index their site.

Scraping G-News is easy enough. I must admit that I had a site a couple of years ago with a page "widgets in the news" that scraped [news.google.com...] and repackaged/reformatted it, complete with adsense ads. Even had it ranking #1 for the phrase 'widgets in the news' for awhile. I dropped the page when the site went through a major redesign - variety of reasons, but in the end I just saw it as too risky for what was overall a good solid and well ranking site. The news page added too little.
Considered using the RSS feed, but the Google branding looked too cheesey...
Now, what do you suppose would happen if I used a similar script to "aggregate" articles from a few European tourist info type sites and slapped a bunch of ads on them. Would that be fair use? Shucks, I'd be providing free traffic wouldn't I?
