April, 2006 Yahoo Update - Pages URL only and/or Not Cached?

[Marcia]

I noticed what seemed to be some new traffic coming from Yahoo, and here it is, announced today in their weather report:

Yahoo Search Blog

I've just been checking sites at Yahoo this week (even wrote down notes), and a couple of sites have switched in and out of not having the index page come up first with a site: search.

What's intriguing, though, is that a lot of pages on a site or two are URL-only, some have the identical "copyright" line picked up as a snippet, and a good number of pages are unavailable in the cache.

Anyone else seeing anything that seems a little peculiar?

I noticed my site made some big jumps in Yahoo serps this week, maybe because of the update?
