You might think that there is a little bit of tit for tat going on between Facebook and Google+, why not it means that we will be getter better features so let battle commence. Anyway, just a few days after Google+ allows users to use a larger image for their profiles, Facebook has done the same. Before the changes, the profile image with Facebook was 130 x 125 pixels, but now the image has a size of 160 x 160 pixels.
It may not be much in the scheme of things, but competition is great for innovation and this means the users get to benefit from changes and additions, keep it going Facebook and Google.
