I'd say it's improving for different categories of searches. Because for a long time users were largely technical, it's search for tech stuff has been pretty good for a long time (in general, there are a few sub-categories in that that have lagged[1]). Where, searching for an author or book might have terrible results. So, when these people say it has improved, they mean it has improved for the kind of searches that that person does. As more people use it, and suggest improvements[2], it will approach being good for all kinds of searches. [1] It still isn't very good at searching for specific error messages. It definitely used to show obscure projects on GitHub way too often. You'd do a search for 'getty' and some 3-commit project with a name containing getty would be the first hit. Also, I think it's actually gotten worse at finding Rails API stuff. [2] It's been a while since I tried, but if you tweet at them with a search term with a poor result, they will try to figure out how to tweak the algorithm to make it better. It's really cool to see them act so directly on your suggestions.
