Issue
When a Steemit user visited the feed of another user (https://steemit.com/@__user__/feed), the title of the page read "My Feed" even though it was the feed of another user. This Github issue describes the problem.
This is a screenshot of another user's feed. Notice that the title of the page is "My Feed". This image was taken from the issue on Github.
Solution
To fix this problem, I modified the PostsIndex page to use a variable containing the username of the feed we are viewing. If that username is the same as the username of the user logged in, it still says "My Feed". Otherwise, it changes the title of the page to "User's Feed".
Whereas the previous code merely checked to see if the user was viewing a feed and automatically labelled it 'My Feed', my code also checks if (account_name === this.props.username). If this is true, the user is viewing their own feed and it says 'My Feed'. In the else case, it sets the page title to account_name + "'s Feed".
