We have two WebmasterWorld threads and a DigitalPoint Forums thread discussing a brief update and bug with Microsoft's Live Search.
We know the last Microsoft Live Search update was about 15 days ago. So it does seem a bit early for another update. We also know that Yahoo updated recently and Google had a PageRank update on the same day. So maybe Live Search felt left out? Just kidding.
The DigitalPoint Forums thread reported an issue with Live Search or MSN Search missing "next" buttons in the search results. While the two WebmasterWorld threads reported the results flipping from one set to a new set of results. Which set of results were positive? It depends who you ask.
The update and bug seem to have been reversed quickly. There was very little discussion around the update. But if I had to guess, if the same thing happened over at Google.com, well - I would guess there would be 20 threads at DigitalPoint Forums and a 10 page WebmasterWorld thread on the topic.
