Why? Because Radio-based blogs—like Scobleizer and Scripting News—use permalink URLs including fragment identifiers. For example, the most recent post on Scoblelizer has a permalink URL of:
This permalink identifies a particular post on the blog’s 31/07/2005 archive page; a browser resolves it by requesting the URL that precedes the # and searching the returned page for the fragment identifier that follows the #.
So, if I form a Technorati search URL by naive concatenation, as I had been doing, you get:
http://www.technorati.com/search/http://radio.weblogs.com/0001011/2005/07/31.html#a10804(no links at time of writing)
Close, but this isn’t actually searching for what I want it to search for. What’s actually happening here is a Technorati search for all citations of the 31/07/05 archive page, followed by an unsuccessful in-browser search of the resulting page for the
What I need to do is have Technorati search for the entire Scobleizer URL, including the fragment; the way to do this is to
escape()the search URL before concatenation, which encodes the # and hides it from the browser’s special treatment:
http://www.technorati.com/search/http%3A//radio.weblogs.com/0001011/2005/07/31.html%23a10804(6 links at time of writing)
That’s better. So, oops; my mistake. And the lesson: beware quick and dirty hacks.
