I was learning the searching function of Technorati and surprisingly found a picture of the library umbralla bag was posted in flickr. In web 2.0, you never know who will comment about your library, and how they will do it. Intersting, should I add comments to this picture? Here is another one related to Eskind, but not tagged.
Just like what is said about Technorati in its help page:
Technorati allows you to find out what people are saying about you, your company, your products, your competitors, your politics and, other areas of interest, on the Internet in real time.
Another paragraph answered my question about RSS and Technorati:
What about an RSS search engine? Is that different from what Technorati does?
Yes. RSS feeds are a subset of the World Live Web. An RSS search engine searches only content structured in specialized XML formats such as RSS and Atom but does not look at a site's HTML or other markup. Not all blogs have RSS feeds, and some sites that are not blogs (such as The New York Times or some online event calendars) do have RSS feeds. Many blogs only send out a small portion or summary of their full postings and leave the full postings on their sites as HTML. Technorati specializes in searching all blogs, not merely those with RSS feeds, and instead of only indexing the RSS feed (often the first few hundred words of an article), Technorati reads all of the HTML code in a blog posting, and also tracks all of the activity around a blog or post such as inbound and outbound links.
