Forums such as Google Web Search Help and Reddit spotted that the I'm Feeling Lucky button on the Google search home page is not working as it did.
In short, you are suppose to type in a query, click the button and be taken to the first site Google lists in their search results. With Google Instant, Google dropped that feature but it did work when you went to settings and turned off Google Instant.
There were also hacks to get it to work.
But now, even with the hacks and Google Instant off, the Im Feeling Lucky button doesn't take you to a site. Instead it takes me to the search results or somewhere else.
For example, if you went to https://www.google.com/search?q=Electric+Universe&btnI=Im+Feeling+Lucky adding on that parameter would typically trigger the feature but now, nope, it doesn't work.
Hat tip to V3.co.uk for writing about this first.
I asked Google for a comment on this and will report back when we hear.
