Technorati Graph Hack

When you do a search in Technorati for a term, it provides a neat little graph of the volume of posts per day containing the search term. However, if the search is for a URL - no graph is produced. It turns out that you can create a graph of link volume by using the following URL:

http://technorati.com/chartimg/<URL>?days=<DAYS>&size=<SIZE>&type=url

The key thing is the last argument above. <SIZE> can be one of (at least) t, s, l and URL is host.domain.tld (I've not yet managed to get it to work with paths).

Here's the graph of links to the Discover Magazine (guess when they switched to the new URL): http://technorati.com/chartimg/discovermagazine.com?days=365&type=url&size=m

Here's Powerset's attention:

BlogPulse never made the distinction between searching for URLs and searching for regular terms - I suspect the Technorati feature just hasn't been publically described for priority reasons as it seems to work fine. I'd love to see them develop their graphing feature further - including options at least for multiple lines and for normalization. I don't really care that that would be a complete copy of ours as they bring a longer window of data in to play which is of interest in itself.

Given the amount of spam in Technorati's index, do you believe that such graphs provide any actual value? When Technorati claims that its index has 70+M blog URLs, doesn't this claim alone negate the results? I worry in looking at these numbers that it's not clear how spam, and more importantly splogs, skews the results. Any thoughts there?
