Answer 1

On my own profile I 'follow' various surnames.  In my case immediate direct line surnames.

When someone adds a new profile with that surname - I get an email from Wiki - giving me the WikiFeed of new content.

It can be useful as they may have just created an ancestor that you might have been looking for.
