Web 2.0 and 3.0
Search Engines

I have been given the task of searching for and recommending touch typing programs for students in our K-2 elementary building.  
I chose to use Duckduckgo (a search engine I have heard about but never used) and Google (my go to search engine.)
I was looking for free typing programs that weren't littered with advertisements. 
The results had to be for younger students and not middle school which is why I chose the word "kids" rather than "students."

Similarities  - When comparing the first few results, I found that both search engines came up with similar sites.  
Both program's results were also appropriate for younger students and most of the results were free typing programs.

Duckduckgo - I was please to find out that this search engine doesn't track the searcher, therefore no follow up advertisements about typing should pop up.  
Even though the first result for Duckduckgo was not a free site, it was clearly labeled as an advertisement, which I appreciated. 

Google - I got many of the same typing sites as found in Duckduckgo.  They were free, age appropriate and fairly free of advertising.  
Google also had hits that included web sites evaluating and recommending typing programs for students such as 
"12 great keyboarding games at educatorstechnology.com." 
I like that Google is not limiting my search to just a specific typing program but included sites that can guide me toward other choices.  
I also like that Google offers suggestions as you type in your query. 
I use that often and it is a great trick for students to use, especially students who have limited spelling skills.   
I have in  the past found that when searching on Google, it is trickier for some to determine which sites might be advertisements and which are not.

In summary - it is nice to be able to use a search engine like Duckduckgo and not be tracked.  
Personally, I will most often use Google as it offers more options and includes a wider range of results.
