Good idea for social interaction.

I am not getting my reputation tab here.

It is good to find consolidated profile information at one place. Text font is looking a bit off. But I think it is a standard font SAP is going to use in future.

Once you upload an image you can not remove it, only override with other picture.

I can see when you restore the screen and you display the menu, it does not look good.

As you can see there is a space on header.

Why can't one update their email address?

When in the profile it's not possible to create a post, ask a question or send a message. This is only available in "browsing mode":
