In February I wrote about Did You Mean search results appearing above normal Google search results. This differed from the presentation of just a link to the Did You Mean search results.

While I understood the potential user benefit, from an SEO perspective, Did You Mean search results could make misspelling optimization far less attractive.
As luck would have it I was able to get an answer on this topic from Matt Cutts.
It's about what I expected. The presentation is relatively new and is tied to an algorithm triggered by some threshold where Google expects a high degree of accuracy in the Did You Mean match. In the end, it probably does deliver value to the user.
I appreciate the response (thanks Matt) and am reminded that SEO is an ever changing endeavor.
