First of all, I like using Pulse.
But today I recognized an issue that should be improved, especially because you wrote about pulse that Privacy matters.
I found out that the Pictures, posted within pulse are public acesseble. You only need the link. I checed it by using the web interface, copying the Picture URL and sending it to a Friend.
Although the Adress is hard to guess, this is NOT the actual security standard in todays web.
I would like to see restricted Access to all content within Pulse. Also https Access should be implemented, but you already told here that this will come with the next release.
I hope this privacy concerns will be heard, an you change this issue.
