Since Google homepage is getting increasingly cluttered with fancy widgets that are not only irrelevant to the core of search but also resource-intensive for an average computer, it is no longer a qualified homepage candidate for those who emphasize on agility in search experience. Search "classic google" online and you will find a lot of people complaining about Google's indifference to suggestions of providing a vanilla search interface.
Let there be LITE.
Inspired by google-classic.com (Obsolete!), I set about building a light-weighted Google Custom Search engine myself. Now comes BadG, which resembles classic Google search in both appearance and function. No navigation bar. No avatar. No sign-in. No social network. No instant search. No auto-completion. No preview. No ads. (Hurray!) Plain but effective. Well, Google might consider it bad, but it suits my needs anyway.
BadG is not associated with Google, except for the mere use of Google Custom Search. BadG is and will remain non-profit. No behavioral data is collected on my part. Please be advised that BadG tends to return fewer results (free of my intervention, of course) than regular Google search.
