If I want to look something up, I always check out wikipedia first. Its not always accurate, but its invariably a lot more accurate on most topics than random information across the web. Its also pretty easy to spot bad quality wiki articles once you get the gist of the site
Its amazing that wikipedia exists - there've been multiple hardcore attempts to kill it over the years for profit, but its still managing to go
Wikipedia is often the last on my goto resources to consult. The information is huge, but writing quality or style often irks me more than I can stand. I I always check Britannica first. If it's not there, then I move on.
