You're just reconfirming my belief that people on this forum look at things the wrong way regarding this thread and Ask.
To 99% of users of search engines, what Ask has done is a huge progression in search. To this 99% some change in algorithm, or an improvement in how Ask relates to webmasters, matters not one jot. Users like whizzy new features and Ask now has this in spades.
I have been using Ask for weeks and have found no dead pages. Most users are not going to find these problems. If you run 100's of searches every day looking for such things then you'll find them! But users won't be doing this. They'll type 'Paris Hilton' into the box and get serps, video, images, news.. WOW!
I'm not having a go at anyone here. I read this avidly and I am very into search. I'm just trying to put the point across that, when discussing the likely success or otherwise of Ask, people posting here are not the users who are going to make or break the issue.
