I doubt anyone has noticed, but I've deleted the 'reaction' footer to my postings. Although I found this feature informative, in recent months there have been problems with it. On multiple occasions, I found that the 'agree' numbers would be reset to zero, particularly on posts that were critical of the Obama Administration.
Whether this was on purpose by Google, or a bug in their widget, I do not know. However, it is a known fact that the folks who run Google are big Obama fans and Democratic campaign donors. I'll leave you to make your own determination.
