Apologies if I came off as being hyper critical, that wasn't my intent. Actually, I'm pretty impressed with what you are doing - I just setup a codio account and submitted a pull request to update the git cheat sheet, just to see how you are doing things. Pretty cool :-)

My only point is that all search engines tend to cannibalise the ones they index to a certain degree when they aggregate or present results from their own website. It doesn't make it wrong to do so, or even unethical. I just think it would be nice if some sort of mechanism could be worked out to encourage people to visit and contribute more to the sites that generate the data being used.

DDG makes it quite plain where the data is coming from, and is very open and transparent with what you guys are doing, so please just take what I wrote as a comment and maybe a request, but certainly not a criticism.

Edit: I just reread my comment and I expressed myself rather poorly I think. The sentence "DDG need to learn how to play nicely..." was not at all what I was trying to convey. DDG do play nicely with others, far more so than anyone else. I apologise for that phrasing, that was unintentionally rude.
