Good grief, Google wished me a Happy Birthday!
The above flashed up when I opened Safari this morning. I don't recall ever giving out that fact to them. I thought I had kept the date between my ears and under my hat.
And here I thought that being one identity among millions I wouldn't be noticed. My apologies +Darko Luketic you were right.
I will have to take a fine tooth comb to my data. I guess it will be an interesting experiment to see if deleting the above will cause Google to 'forget'.
