Ask.com went back to its roots and enhanced the snippets for search results if the query is a question. Snippets are usually excerpts that include your query, but Ask.com replaced them with the actual answers, as you can see if you search for [how to tie a tie]:
"Presenting direct answers to your searches, front and center, has always been at the heart of the Ask.com experience, and we push further down that path today with the introduction of three new answer technologies: DADS, DAFS, and AnswerFarm. These technologies take both structured and unstructured data, and - instead of delivering a title and description for each document - they deliver answers," explains Ask's blog. This is a clever idea, but Ask.com only shows at most 2 results with enhanced snippets.
The new feature is part of a broader update that mixes specialized search results with organic web results, much like Google's universal search. Ask.com goes one step further and almost eliminates standard, as you can see if you search for [Madonna]: in the top 10 results, you can find 4 web search results, one direct answer, image results, news results, event listings, video results and an encyclopedia result.
