An anecdote, but it's really difficult to search for information on git. Pretty much everything I find is specific to GitHub. Though that might be a problem with me still using Google to try to find information.
This is getting off-topic, but at a certain point Google's results started to feel less and less relevant. Strict keyword matching stopped becoming a feature since it started to "guess" the "hidden meaning" behind your searches, modifiers like "include this exact text" and -"exclude this" stopped being supported and the amount of crap it throws in the search results that are not links to websites became distracting and annoying much of the time rather than useful.
