I used to hide it in Flickr due to an obsession with internet privacy, without thinking through if there were are real implications. Privacy just for privacy sake. I relaxed that more recently and changed my default settings on Flickr. After looking at it again as a result of this post , I have just realised that since I have been using Photoshop (just a couple of months) that the default for "save to web" is to strip the metadata. I will play with these settings and change this.
