Commission collections and ethics aside, I actually cannot understand the venom towards Ask (its search results). I believe in keeping web searches open with multiple choices made available to users, so I actively support all viable alternatives (meaning I use Ask, Blekko, ddg, lycos, yahoo (bing) among others instead of Google for regular everyday searches). Ask search results are very much comparable to Google's, i.e., the search is not "inferior" as claimed.
As for ads, google's adsense ads are just as much in-your-face as the others (ymmv), so don't think this point is such a big thing either as claimed.
