However, I have a question about how this will work with weblogs without a top-level domain name. I'm guessing but I reckon Dave's using Google's site search feature to narrow search results to a particular weblog. For example:
narrows Google's search result to only those hits on scriptingnews.userland.com. This is a neat feature in Google.
Unfortunately there's a gotcha. Site search doesn't work with weblogs (or any other Internet site) that don't have a top level domain. For example:
site:radio.weblogs.com/0001161/ is not valid, only site:radio.weblogs.com is but that's no use as there are thousands of weblogs on that server.
Hmm, maybe the only solution is for webloggers to get themselves a top-level domain name? Or could Google be persuaded to extend their site search feature to URL fragments rather than just the domain name?
