Thanks for sharing those two
I get the sense that Snipplr covers one type of thing (snippets), while Google's Code Search covers another type (full packages?). I didn't figure out what Koders covers, but I got the sense that it at least covers the kind of thing that Google's Code Search does.
Does this impression seem accurate?
My favorite test search at the moment is for "beget" in JavaScript -- for this case, I seem to get more results from Google's Code Search than the others (are the results relevant?...good question!). I wonder if anyone has done a more relevant comparison
