WAY back in November of 2010 I wrote about Blekko while it was still in beta and never really gave it much thought after that. Recently Blekko has gone through some changes to make search results for user friendly and different from what we are used to on other search engines. Results from searches are now automatically broken down into various categories of different content. When you search for something you get both the top and latest results as well as specific searches related to your original search. This new layout allows for more results on one page and the search will automatically adjust to your screen size for mobile devices. Users can also search Blekko for images and videos as well.
If you have never seen Blekko and are unsure of what a slashtag is, basically it allows users to easily create a custom search and helps to narrow down a search. The slashtags are a tool that is used to help filter search results while helping to eliminate spam and content farms. For more information about slashtags, check out the tutorial.
