	accounts aren't linked. so when user logs in  with facebook and onother time with twitter and then with goole, his credentials are stored 3 times as 3 different users.   As a result user might appear like 3 differenet users.

	Design flaws. Any user can edit, delete, and create posts. Even if not logged in

	Comments aren't stored properly
	Comments aren't displayed properly, user is unable to sort them by date in both directions.
