Things are getting interesting. Yahoo's new My Web 2.0 is now in beta, which taps into your already trusted networks to (ideally) give you more relevant search results based on what the folks you know have recommended. I've had the chance to start playing around with it a bit, and it seems so far to be the adorable lovechild of traditional search and social bookmarking services. It brings to regular search the spicy flavors of trust and serendipity and, praise be, folksonomy (it's true, I'm a fool for tags). You can save, tag and annotate your Yahoo search results, flag them as public or private, and narrow a search to give results only from the subset of pages your contacts have saved. Again, bless them, they're providing an open API for developers to tweak, so look for some sweet new applications to be built up on top of this. They also articulate a long range goal of seeing communities build up their own localized search engines on specific topics or areas of interest — an information management goal that tugs on my little secretly (shhh) hippie heartstrings.
