Today is the last day you will be able to use Yahoo Site Explorer.
Yahoo announced late on Friday that they are closing it down today, November 21st. They said:
With the completion of algorithmic transition to Bing, Yahoo! Search has merged Site Explorer into Bing Webmaster Tools. Webmasters should now be using the Bing Webmaster Tools to ensure that their websites continue to get high quality organic search traffic from Bing and Yahoo!. Site Explorer services will not be available from November 21, 2011.
This comes with no surprise. Yahoo notified everyone that it would happen this year but since today is the day, it is some what of a shocker that it has finally happened. It is basically the last nail in the coffin for Yahoo Search.
Site Explorer was launched in 2005 as one of Tim Mayer's babys at Yahoo. I personally am very sad to see it go, but I am sure it upsets Tim a bit more.
Forum discussion at WebmasterWorld and DigitalPoint Forums.
Update: As of Tuesday, November 22nd, it is now closed and here is what the closure page looks like:

Nice tool but has a very limited index. They may benefit from that open source index running on amazon.

Yahoo! site explorer is another one of those great web tools that we'll have to find a replacement for, because Google's link count is up and down like a Bride's nightie!

I was noticing lately Yahoo Site Explorer was not updating a lot anymore for my new backlinks. It was fantastic some time ago. Still, I am sad it is going..

I knew this was going to happen, but I am still sad to see it go. I think that they could have left it up and running. I am not a fan of bings tools, but I guess I will have to adjust to it.

I would like to know that from now in Bing webmaster tool we will see traffic and complete detail from both major search engines, so will the result be shown separately that this was searched in Bing and this keyword was searched in Yahoo, visitors from Yahoo and number of visitors from Bing.

Nightmare, SEOmoz's open site explorer isn't too bad but it needs to update more often, I like to be able to find out how many links my linkbaits get a few days after they are published.

I just got the email from Majestic, yep they are the only real competition except for open site explorer. Should be interesting to see how this changes trends in search optimizing, as our keywords and apparent site influence as well as back link targets may change with the move to new metrics tools like Majestic

It seems there are more alternatives to YSE than many realized, and more are coming to the foreground by the week. We took a look at a the major players here and have about 5 or so additional backlink tools and services yet to review. http://siteexplorer.co/top-10-yahoo-site-explorer-alternatives/ I think a feature matrix will help clear things up a little bit in terms of how the competition stacks up compared to the original tried and true Y! Site Explorer.

It is not a good day, but there are many tools can replace yahoo site explorer, siteexplorer.info can do that, and i think it is more better.
