The thing I love most about Blekko is its /date slashtag. But on the other side, it's one of the only clear advantages it has over other search engines; its general slashtags include too few sites. There are some rare occasions where its scarce list of sites comes in handy - such as when you need a rough timeline with /date, and where a single story is parroted, such as Reuters, AP, US Weekly, and People Magazine.<p>DDG is generally a nice alternative to Google, and its bang commands are invaluable, but it falls short when it comes to delivering relevant hits to my queries.<p>DDG is my default search engine in browsers, but most of my general queries begin with "!g".<p>None of the three are mutually exclusive, and I'm glad to have all of them. You shouldn't dismiss any of them nor use them exclusively.
