Very interested to see how accurate this is in practice. Could really help cut down the google -> stack overflow -> copy -> paste round trip time.
I think it would be really cool to be able to see how others (publicly or privately) use certain APIs. I think it would help with faster adoption and "crowdsourcing" documentation. I can't tell you how many times I have had to Google/Stack Overflow Spring (and other library) specific things because I just wasn't sure if it could be used in a certain context based on the documentation present in an IDE or the project's documentation.
Sometimes people need to maintain systems that have generated millions in revenue even if they use APIs that suck, or languages that you might not find intuitive.
Tickling aside, anything that removes humans from the process looks good to me.
